Inphyy,
If being thrown out is a real concern for you, which it sounds like it is, I'd contact Children's Hospital Transyouth clinic and explain your situation. The thing about most lgbt-youth shelters is that they are funded by HIV prevention funding from the State. Budget cuts are coming down hard by the end of the year. You waiting until you get thrown out to gather information would probably be a bad idea since places that might be able to house you will probably be cutting numbers of intakes by the end of the year.
My suggestion would be to do what you have to survive at home for the time being. Trust me, it's a bad, bad time to be a homeless trans-youth. Ontario, Chino, Riverside, very bad. LA, not much better. You are needing to be who you are but having food, clothing and shelter when you are <18 trumps that. Living on the streets might seem like a better alternative than the mess you are in now. It isn't, it really isn't. There's some good advice from people in here, in this thread Inphyy. Be well, Meghan
