Had two roommates last year, one I'm friends with (but he's in my major, I would've been friends anyway) and the other was an absolute nightmare to live with. I don't know how I made it through, honestly.
Sorry to hear that Grav. I have had pretty decent roomates so it has been actually fun for me. Living with people you want to live with also helps the situation, so if you are looking for something after your first year, then thats the way to go.
