Therapy for Seasonal Affective Disorder in Melville, NY – Serving Long Island and New York

Every year, as the days get shorter and the weather turns colder, you feel it happening again. Your energy drains away. Your mood darkens. Activities that normally bring you joy feel flat and uninteresting. You sleep more but never feel rested. You want to withdraw from everyone and everything, and getting through a normal day feels exhausting.
But it will eventually go away. It typically does in the spring/summer months.
This is seasonal depression. Seasonal depression, also called Seasonal Affective Disorder (SAD), isn’t just “winter blues” or a preference for sunny weather. It’s a form of depression that follows a predictable pattern, typically starting in late fall or early winter and lifting in spring or summer. And while it may be temporary, the impact it has on your life during those months is real and significant.
You don’t have to suffer through another winter feeling miserable, isolated, and stuck. Seasonal depression is treatable, and with the right support, you can reduce symptoms, maintain your quality of life, and get through the darker months without losing yourself in the process.
Heart in Mind Psychotherapy offers specialized treatment for seasonal depression on Long Island, helping clients manage symptoms, challenge the patterns that make depression worse, and maintain connection and functioning even during the most difficult months.

What is Seasonal Depression?
Seasonal Affective Disorder (SAD) is a form of depression that occurs at the same time each year, typically beginning in late fall or early winter and improving in spring or summer. A small percentage of people experience the opposite pattern, with depression occurring in summer, but winter-pattern SAD is far more common.
Seasonal depression isn’t just feeling a little down or wishing it were warmer outside. It’s a genuine depressive episode with symptoms that can include:
- Persistent Low Mood – Feeling sad, empty, hopeless, or irritable most of the day, nearly every day.
- Loss of Interest or Pleasure – Activities you normally enjoy feel boring, pointless, or like too much effort.
- Low Energy and Fatigue – Feeling exhausted even after a full night’s sleep, struggling to get out of bed, or feeling like everything requires enormous effort.
- Changes in Sleep – Sleeping much more than usual (hypersomnia) and still feeling tired, or having difficulty waking up in the morning.
- Changes in Appetite – Craving carbohydrates and comfort foods, overeating, and weight gain.
- Difficulty Concentrating – Trouble focusing, making decisions, or completing tasks that normally wouldn’t be challenging.
- Social Withdrawal – Wanting to isolate, avoiding social activities, and feeling disconnected from others.
- Feelings of Worthlessness or Guilt – Negative thoughts about yourself, feeling like a burden, or ruminating on past mistakes.
- Physical Heaviness – Feeling like your arms and legs are weighted down, making movement feel difficult.
Seasonal depression is caused by reduced sunlight exposure during fall and winter months. Less sunlight affects your circadian rhythm (your body’s internal clock), disrupts serotonin production (a neurotransmitter that regulates mood), and causes changes in melatonin levels (which affects sleep and mood). These biological changes create the symptoms of depression.
Seasonal Depression and Daily Functioning
Seasonal depression doesn’t just make you feel sad – it affects every area of your life. During the months when symptoms are active, you might struggle with:
- Work Performance – Difficulty concentrating, missing deadlines, reduced productivity, or calling out sick more frequently because you can’t face going in.
- Relationships – Withdrawing from your partner, family, and friends. Feeling irritable or emotionally flat. Being less available or engaged in your relationships.
- Parenting – Finding it harder to be patient, present, or energetic with your children. Struggling to keep up with the daily demands of parenting.
- Self-Care – Letting exercise, healthy eating, and other self-care practices fall away because they feel like too much effort.
- Social Life – Turning down invitations, canceling plans, and isolating yourself from the people and activities that normally bring connection and joy.
- Hobbies and Interests – Losing interest in activities you normally enjoy, which makes the winter months feel even more empty and monotonous.
The impact of seasonal depression is compounded by the fact that it happens every year. You know it’s coming. You dread it. And even though you know it will eventually pass, living through four to five months of depression annually takes a serious toll on your mental health, relationships, and quality of life.
What Causes Seasonal Depression?
Seasonal depression is primarily caused by reduced sunlight exposure during fall and winter months. This affects your body in several ways:
- Disrupted Circadian Rhythm – Your body’s internal clock relies on sunlight to regulate sleep-wake cycles, hormone production, and mood. Shorter days and less sunlight throw this rhythm off, which can trigger depression.
- Reduced Serotonin Production – Sunlight helps your brain produce serotonin, a neurotransmitter that regulates mood. Less sunlight means lower serotonin levels, which contributes to depression.
- Increased Melatonin Production – Darkness triggers melatonin production, which makes you feel sleepy. Longer nights and less daylight mean your body produces more melatonin, contributing to fatigue and low energy.
- Vitamin D Deficiency – Sunlight exposure helps your body produce vitamin D, which plays a role in mood regulation. Less sunlight during winter can lead to vitamin D deficiency, which is associated with depression.
- Season-Related Traumas – Some people also experience seasonal depression not because of light exposure, but because they
Certain factors increase your risk of developing seasonal depression. Living on Long Island, where winter days are very short and the sun is often covered by clouds is part of the problem. Family history and other mental health challenges may also play a role. Some people struggle with mild depression all year that they have learned to manage, but find that it gets much worse during the winter.
In any event, seasonal depression is treatable, and – even if it does go away in spring/summer – deserves to be treated.
How We Treat Seasonal Depression
At Heart in Mind Psychotherapy, we use evidence-based approaches that have been proven effective for seasonal depression. Treatment is tailored to your specific symptoms, patterns, and goals.
Cognitive Behavioral Therapy (CBT) for Seasonal Depression
CBT is highly effective for seasonal depression. A specialized form of CBT has been developed specifically for SAD, focusing on the thoughts and behaviors that contribute to depression during winter months.
In CBT for seasonal depression, you’ll work on:
- Identifying Negative Thought Patterns – Recognizing thoughts like “I can’t get through another winter like this,” “Everything is pointless,” or “I’m going to feel this way forever.”
- Challenging Depressive Thinking – Testing whether your thoughts are accurate or whether depression is distorting your perspective. Learning to recognize that “I feel hopeless” is different from “the situation is actually hopeless.”
- Behavioral Activation – Depression makes you want to withdraw, sleep more, and avoid activities. But avoidance makes depression worse. Behavioral activation involves gradually increasing engagement in meaningful activities even when you don’t feel like it, which helps improve mood and energy.
- Building Winter Routines – Creating structure and habits that support your mental health during difficult months, like morning walks outside (even on cloudy days), maintaining social commitments, and scheduling activities that provide a sense of accomplishment or connection.
- Light Exposure Strategies – Increasing your exposure to natural light by spending time outside during daylight hours, sitting near windows, and making your home environment brighter.
CBT teaches you skills that you can use not just this winter, but every winter going forward. It helps you take an active role in managing seasonal depression rather than passively waiting for spring to rescue you.
Behavioral Activation – Taking Action Even When You Don’t Feel Like It
One of the most powerful components of seasonal depression treatment is behavioral activation – the practice of engaging in activities even when depression tells you not to.
Depression creates a vicious cycle: you feel bad, so you withdraw and avoid activities, which makes you feel worse, which makes you withdraw even more. Behavioral activation breaks this cycle by helping you:
- Identify Values-Based Activities – What matters to you? What used to bring you joy or meaning? Even if those activities don’t feel appealing right now, they’re important to maintain.
- Schedule Activities Intentionally – Rather than waiting until you “feel like it,” you schedule activities and commit to doing them regardless of how you feel in the moment.
- Start Small and Build Gradually – You don’t have to take on major activities. Start with small, manageable steps like going for a 10-minute walk, calling a friend, or spending 15 minutes on a hobby.
- Notice the Impact – Pay attention to how you actually feel after engaging in activities, not just how you felt beforehand. Most people find that they feel slightly better after doing something, even if they didn’t want to do it initially.
Behavioral activation is challenging because it requires you to act opposite to what depression is telling you to do. But it’s also one of the most effective tools for managing seasonal depression.
Light Therapy and Environmental Changes
While therapy is our primary focus, we also educate clients about complementary strategies that can reduce seasonal depression symptoms:
- Light Therapy – Using a specialized lightbox (10,000 lux) for 20-30 minutes each morning can help regulate your circadian rhythm and increase serotonin production. Many people notice improvement within one to two weeks.
- Maximizing Natural Light – Spending time outside during daylight hours (even when it’s cloudy), sitting near windows, and keeping curtains open to let in as much natural light as possible.
- Creating a Brighter Environment – Using brighter bulbs at home, painting walls lighter colors, and removing visual clutter that makes spaces feel darker.
These strategies work best when combined with therapy, which addresses the psychological and behavioral aspects of seasonal depression.
Mindfulness and Self-Compassion
Seasonal depression often comes with harsh self-criticism. You might blame yourself for not having more energy, for struggling with things that feel easy in other seasons, or for “letting” depression affect your life again.
We help you develop:
- Self-Compassion – Recognizing that seasonal depression is a medical condition, not a personal failing. Learning to treat yourself with kindness rather than judgment during difficult months.
- Mindfulness Skills – Staying present with what’s actually happening rather than getting lost in catastrophic thoughts about how long winter will last or how bad you’ll feel.
- Acceptance – Acknowledging that some discomfort and difficulty are part of seasonal depression, without adding suffering through resistance or self-blame.
Self-compassion doesn’t make depression disappear, but it reduces the additional pain that comes from fighting yourself or feeling ashamed of your struggles.
What to Expect from Treatment
Seasonal depression treatment works best when started before symptoms become severe. Ideally, you’d begin therapy in early fall – before the depression fully sets in – so you can build skills and implement strategies proactively.
If you’re already deep in seasonal depression, treatment can still help. You’ll likely notice improvement within a few weeks as you implement behavioral activation, challenge negative thoughts, and increase light exposure.
Treatment involves:
- Regular Therapy Sessions – Typically weekly or biweekly, depending on symptom severity.
- Between-Session Practice – Implementing behavioral activation strategies, tracking your mood and activities, and practicing the skills you’re learning in therapy.
- Preparation for Future Years – Developing a plan for how you’ll manage seasonal depression next year, including when to start light therapy, what activities to maintain, and early warning signs to watch for.
Together, seasonal affective disorder doesn’t have to control your winter life. We can reduce its severity, maintain your functioning during difficult months, and prevent the downward spiral that makes depression worse.

FAQs about Seasonal Depression Treatment
Frequently Asked Questions About Seasonal Depression Treatment
How do I know if I have seasonal depression or just regular depression?
The key distinguishing feature of seasonal depression is the predictable pattern – symptoms start around the same time each year (typically late fall or early winter) and improve at the same time each year (typically spring or early summer). If you notice that your depression lifts when the seasons change and returns the following year at the same time, that’s a strong indicator of seasonal depression. Regular depression doesn’t follow this seasonal pattern. However, some people have year-round depression that worsens in winter, which is slightly different from pure seasonal depression. A therapist can help you identify which pattern applies to you.
Why should I bother treating seasonal depression if it goes away on its own?
While it’s true that seasonal depression typically improves in spring, that doesn’t mean you have to suffer through four to five months of depression every year. Treatment can significantly reduce the severity of symptoms, help you maintain functioning at work and in relationships, and prevent the depression from worsening over time. Four to five months is a long time to live with depression, and the damage it causes – strained relationships, reduced work performance, withdrawal from activities – doesn’t automatically disappear when spring arrives. Treatment also gives you tools to manage future winters more effectively, so you’re not starting from scratch each year.
When should I start treatment for seasonal depression?
Ideally, you’d start treatment in early fall, before symptoms become severe. This allows you to build skills, implement strategies like light therapy, and take a proactive approach rather than waiting until you’re deep in depression. However, if you’re already experiencing symptoms, it’s not too late – treatment can still help reduce severity and duration. Many people also benefit from continuing some level of therapy support year-round or returning to therapy each fall as a preventive measure.
What is light therapy and do I need a special lamp?
Light therapy involves sitting in front of a specialized lightbox (10,000 lux) for 20-30 minutes each morning. The bright light helps regulate your circadian rhythm and increase serotonin production. You do need a specific light therapy lamp – regular household lights or tanning beds don’t work for this purpose. Light therapy lamps are widely available online and in stores. Many people notice improvement within one to two weeks of consistent use. While we focus on therapy, we can provide guidance on how to incorporate light therapy as a complementary strategy for managing seasonal depression.
Is seasonal depression the same as vitamin D deficiency?
Low vitamin D levels can contribute to seasonal depression, and many people with seasonal depression do have vitamin D deficiency due to reduced sunlight exposure. However, seasonal depression is more complex than just vitamin D deficiency. It involves disrupted circadian rhythms, reduced serotonin production, and changes in melatonin levels. While taking vitamin D supplements may help, they’re typically not sufficient on their own to treat seasonal depression. A comprehensive approach that includes therapy, light therapy, and lifestyle changes tends to be most effective.
What insurance do you accept? Do you work with NYSHIP?
Yes, we work with NYSHIP and are happy to help you understand your out-of-network benefits. We provide a free analysis of your out-of-network benefits as part of our initial consultation, so you’ll know what to expect regarding coverage and costs before you begin therapy. We can provide you with the documentation you need to submit claims for reimbursement through NYSHIP. If you have questions about insurance or want to discuss your specific coverage, please reach out and we’ll be happy to help clarify what your benefits include.
Can I do therapy via telehealth if I don’t want to leave my house in winter?
Yes, we offer teletherapy for clients throughout New York. Virtual sessions can be particularly helpful for people with seasonal depression who find it difficult to leave their home during the darker, colder months. Teletherapy provides the same quality of treatment as in-person sessions, with the added convenience of attending from wherever you’re most comfortable. Many clients start with teletherapy during the winter months and transition to in-person sessions when the weather improves, though you’re welcome to continue with virtual sessions year-round if that works better for you.
Does seasonal depression get worse as you get older?
For many people, seasonal depression does tend to worsen with age if left untreated. What might start as mild “winter blues” in your twenties can become more severe depression by your forties or fifties. This is one of the important reasons to seek treatment rather than just accepting seasonal depression as inevitable. By addressing it proactively – through therapy, light therapy, and behavioral strategies – you can prevent this progression and maintain better mental health during winter months as you age. Early intervention and consistent management make a significant difference in long-term outcomes.
