Getting bullied

I get bullied a lot and called gay because I am smaller and not into sports and because the people in my school are assholes. Last year my English teacher totally picked on me too for no reason at all, like when we were doing class readings he would make me do the girl parts so everyone would laugh. He made it all into a big joke and when I complained to the principal they totally took his side and we had this meeting where he gave me this phony sincere apology and everyone believed him that he was just trying to be a fun teacher but then after that he would stare me down in class and in the hall and it was scary. He hates me and I don't know why. This year he is my home room and English teacher and I am really scared of what is going to happen. My parents think I am making it all up for 'drama'. I don't know if I can take another year of this. How do I get him to back off without making the situation worse than it already is? I am also considering moving to stay with my cousin and working while doing my GED if it doesn't get any better.
