OP don't you think you'd be better off trying to make the best of where you are and additionally make some friends on your course/in societies?
Your flat can't be all that bad, after all, your experience at Uni in general is what you make of it really. Can you socialise more wih your flatmates and make more of an effort? From your previous threads you sound like a bit of a social butterfly. I can't help but feel that you're shifting the blame onto others unfairly here. I really doubt that you're living in a flat which is 100% full of boring, unfriendly people?
