Seasonal Depression
Seasonal depression — clinically, major depression with a seasonal pattern, still widely called seasonal affective disorder or SAD — is depression that follows the calendar instead of your circumstances. For most people it arrives as daylight shrinks in fall and winter: mood drops, energy drains, and sleep and appetite climb. Texas winters are mild, but the days still get hours shorter, and a low stretch that repeats at the same time year after year is the tell. A smaller number of people get the summer version instead. Either way, it's a recognized, treatable form of depression — not a character flaw, and more than just "the winter blues."
Common signs
- Low mood that returns around the same season each year
- Sleeping much more than usual and still waking up tired
- Craving carbohydrates and gaining weight through the season
- Losing interest in people and activities you normally enjoy
- Low energy and heaviness — getting through the day feels like wading
- Trouble concentrating, especially on grey, short days
- Withdrawing socially — "hibernating" until spring
- Symptoms lifting as the season changes, then returning the next year
How therapy helps
Treatment works on two tracks: the depression itself, and the season driving it. Bright light therapy — sitting in front of a high-intensity light box shortly after waking — is a standard, well-supported tool for the winter pattern, and a provider can help you use it correctly: dose and timing matter, and it isn't right for everyone, especially with bipolar disorder or certain eye conditions. CBT adapted for seasonal depression teaches you to catch the withdrawal spiral early and deliberately build activity and daylight into the darkest weeks. Antidepressant medication helps some people, and a prescriber may suggest starting it just before your difficult season rather than waiting for symptoms to land.

When to seek help
If the same low stretch has arrived two or more years running, don't wait for this year's edition — reach out in early fall, before symptoms peak, so a plan (light, therapy, or medication) is already in place. Reach out any time low mood lasts more than two weeks, interferes with work or relationships, or includes thoughts of harming yourself — in which case call or text 988 right away. And if your low seasons come with stretches of unusually high energy, racing thoughts, or barely needing sleep, tell your provider: that pattern changes the treatment, especially for light therapy.
