It's tough for anyone to live in California as it is so expensive. I lived with my grandpa when I needed to be in LA, so I got really lucky. My advice would be to save up so you know you have money to pay rent/essentials for a few months. I would also try to get a few friends to room with you so you don't have to pay rent all on your own. If you have a job now, sometimes you can ask to be transferred to a new area which would give you some safety for having a job there. I think the biggest help is splitting the cost with friends though! Good luck!
