If you parents are homophobic and you think they will react strongly, I suggest NOT telling them until you are self-sufficient. I understand not wanting to live a lie, etc, but you have to make sure that you keep a roof over your head, and food on your plate. In the meantime, work hard at school so that you can get into a decent college and figure out how to turn your education into gainful employment. When you're on your own, then if they react badly, at least you can take care of yourself.
