My parents have said if I go out with anyone except from our culture they will disown me. There's a guy at school that I really like. I don't know what to do. I'm also very mad at them for putting me in this kind of position.

These are cross-cultural issues. Many cultures are fierce about wanting children to exclusively date and marry those of the same culture. You are going to have to think with your heart. Yes, it's unfair, but it's your reality.
