Uh oh- friend with food disorder?

Wow. You are right it's not good. Does she Binge eat too? That could be extremely serious. But you don't want to scare her family if it's just an attention thing. If it's been going on for a while and she doesn't snap out of it, I would tell her parents first, she will not like it and feels she is betrayed, but when you deal with someone with an eating disorder no outcome is very pretty. I would definitely keep your eye on her and then decide when it's better to tell her parents. Only because she's going to be really mad that you told. But do not let that scare you because you could be saving her life!
