How to live with your parents?

Not to sound like every other melodramatic, angst-ridden, teen, but I don't think I can handle living with my father much longer. He's always depressed, and if he isn't he's angry and violent. I'm constantly in a bad mood because he is, and have to stay in my room 24/7. My mom won't divorce him either. Does anyone have any suggestions on how to deal for the next five years? Thanks!
