How can I have a better attitude towards my friends?

How can I have a better attitude towards my friends? Im ery close to mmy friends, but after I told them about my problem( being bulimic). Its been like about a month since I've told them, but now, lately the have been getting relly irritating. They always ask me wats wrong..when nothing is wrong. But then when I acually do need them to talk to and be ther for me..ther not. and I cant relly get over the fact that some of them are really selfish, and that last year they hated me. I mean we got to know each other a lot better and they were really good friends. But there just relly selfish rite now. What can I do to get closer to them again?

well if you feel like you are not close enough then just tell them face-to-face that you dont feel that you are close enough and that is all I can tell you so hope it works
