Communal living is not a bad option but you should get a handle on your depression before you try that so it does not interfere with your ability function within a group. Buy some bulk items cheap, mark em up and sell them at a flea market or something. Get a started tattoo kit and learn to scratch. Tat artists usually have no problem with money or getting laid. Get laid, nothing better for depression than some vitamin P. Read "as a man thinketh" by james allen while you are figuring shit out.
That's usually the case when people ask the question in the thread title. I guess, just live off your parents. Take on hobbies.

I can see where you're coming from but I've known too many fun bums that have no jobs or place of their own and still get plenty of pussy clear into their 30's. sometimes you gotta make it happen.
I know how it feels to be a loser. I'm a loser too! I guess we need a new perspective that can only be obtained through Vitamin "E". E is for MDxx. Only then will there be motivation to improve ourselves.
