I'm usually depressed in the winter. Thanksgiving & Christmas times are the worst, February is better, then the beginning of March always sucks for me. Mid April through June is usually my manic season then July though September is a mixed bag October is okay then November starts my depression again.

This last year was weird for me even... I was depressed all year until my recent bout with mania (In September which was very weird for me). We had so much rain & nasty weather through the spring & summer though, and I was battling a lot of physical medical issues so I think that triggered more depression for me this year). The sun finally came out late August/September & I went manic. So maybe I have SAD, as well? Never was diagnosed with it though.
