I don't know how I'm going to tell my parents, any good suggestions?

Cut them off. Don't make any attempt to see them or talk to them. If they want to see you, let them make the move. And if they are nasty, cut the visit or call short. Sooner or later, they'll get the message. It's one of those Let them go, and if it's meant to be, they'll come back situations. Sometimes even parents have to be trained like children to treat people reasonably.
