You're 19. You should have moved out a year ago.

Don't run away. Prepare to move. Research jobs, and apartments. Suffer through this semester at home, then take the next semester off so you can move and start working. Then pick back up at CC once you're settled.

Or, just move to campus and keep studying. Your parents can't stop you. Your school can help you find a job. Transfer to a major you like. But don't pick one that that won't be useful later on.

Right away, without telling your parents, go to the bank and open a checking account in your name only. Put the 13k there where nobody else can get to it. Then a savings account, too. Learn how to budget right away, that 13k will not last long.

Also, find a mental health counselor. You badly need one. Your school should be a source for that. They probably have an LGBT support group or club, too. Go there.
