What do you do to improve your mood?

I’ll spare the details of why I’m in a down mood, I’m sure a lot of you have seen my previous posts and get the gist of it already. Well essentially I’m working on fixing the things that have me depressed (that I’m able to) but its slow going and my mood has not really improved. What individual activities do you do to improve your mood? Running isn’t really an option, its cold outside. I’ve played games with friends and stuff, but its actually left me feeling sadder. I dunno, I’m a mess…. Suggestions?
