I always get depressed in September. The summer is ending, and everything starts dying. October really depresses me even more, as the garden plants die and the trees loose their leaves. Daylight is so much shorter, and you can't spend as much time outside. The way I get over it is looking forward to spring. I actually feel better once winter kicks in. Snow doesn't bother me, but winter does go on a little too long here in upstate New York. But the longer winter goes, the closer we get to spring.
