Please don't think this is a comedy option.

What do you think about running? Some people swear that it cures depression. I can attest that the runners high makes you feel wonderful. If you're beginning there is Couch25K that's a great way to start so you don't hurt yourself. You can push yourself too hard, it helps you pull the reigns back a bit. Give it 3 months and see if it helps.

I know you are an atheist and Jewish but you could also try church. If you'd like to discuss this PM me.
