Is there a cure for the wintertime blues?

My SADness is setting in already. It’s not crippling but I am in my bathrobe at 5 p.m. I keep Christmas and Chanukah pretty simple but I just don’t feel like getting started this year. (There is a personal sorrow as well that I don’t want to share.)

I’m ok and well enough but I am a little down. Humor and nurturing suggestions are welcome.
