Its a tough situation, you got screwed by being born in LA.
What do you mean there aren't any job opportunities available, do you not have enough education or skills or are you saying the job openings just don't exist? The latter I'd find hard to believe.
There are a few options but none of them are great, you could live in your car for a few months to up the money you would be spending on rent. You could couch surf or find someone willing to let you crash at there's for a while. You could see if there are any programs in areas with jobs that match young people with the elderly for reduced or no rent. I've heard of these sorts of programs in the UK and they seem like a pretty good setup.
