My question is this. If this girl is spiteful and obviously a big trigger for you, is it possible for you to find another roommate? If your goal is to sincerely to recover from this disorder, the key is to try and surround yourself with positive people who won't make it worse. I know that this is sometimes easier said than done, and everyone's living situation is different. But if you're able to find a new living situation, I say go for it! Good luck with your recovery. I've successfully recovered from anorexia and bulimia, and have been free of any eating disorder for over 7 years now. It can be done!!!
