My Psychiatrist Told Me Episodes Are Seasonal?

It's not everyone, but I think it's common. I know a lot of people have like a time of year thing even if it's not textbook seasonal affective. For me, it's pretty stereotypical seasonal and affected by light. (Look up information about light,seasonal affective, and circadian rhythms) there is a lot of stuff out there. I started off plain seasonal affective which escalated to bipolar when I had a 3 month episode of mixed/ mania. My symptoms aren't always based on the season, but it's a relative pattern.

My depression starts in late November/early December, (though I think many people are in October). Symptoms vary from very mild to very severe, psychotic, or mixed, though I've had a couple of normal winters.

Most severe in January, but tends to last at least through March, (longest ever through June, but my situation sucked and I wasn't used to my mind or body yet.) I've tended to be normal in Aprils and Mays, but earliest hypomania started in May. June and July I can be as varied as just happy, normal, upbeat, to hypomania. My one long full blown mania episode started in June, and I was very mixed and agitated and sleepless through August.. (I was actually sitting in a darkened room a lot that August, like a natural reaction to too much light I think. Dark therapy instead of light therapy I guess. )
(so, I don't do an exact equinox pattern where it's worst on the darkest days and the lightest days, I tend to run later.)

September is by far my favorite month of a year. Some relaxation, sleep, upbeat mood, sometimes hypomanic, but mania that year lasted through half of September. I've rarely had an episodic October.

I try not to assume anything about the month I'm in so it doesn't become a self-fufilling prophecy, but in short, yes. Season is a very real trigger and it's a common trigger for a lot of people I believe.

@Anyone
yeah. that makes a lot of sense, thanks for your response.
i'd say November is when it gets depressive for me, and gets better around christmas and new years, but i'm the same as far as April goes. i definitely have a tendency to become hypomanic and growing more and more manic until Summer comes around
i haven't looked into seasonal affective disorder, mainly because my psychiatrist ruled it out right off the bat
