i also have seasonal affective disorder and know how bad the depression in the winter especially can get. i don't like cold days either. i try to stay in the house as much as possible and get exercise from an elipitical machine. i hate the level of depression gets, so low, i can't take it anymore sometimes and landed in the hospital a few times because of the depression. i havn't been there for a few yeas now, but feel like i need the hospital almost every day, but i fight the feeling.
