I'm a summer person and I'm affected by it too. I start getting the winter blues after the fall time change. On the brighter side, the winter solstice is next week and that is the turning point when the days start lengthening again.

HURRY, SPRINGTIME!

I always get depressed on rainy/cloudy/foggy days. I think the weather definately darkens the mood. I'm sure statistics prove it.

I love the rain so it doesnt make me more depressed, I like it when it rains and Im depressed actually

It get depressed when its sunny outside.. I like it when it's dark. When it's sunny, I feel like I dunno... just depresses me.
