My sister has always been slim but now it's to slim. She talks about her weight a lot to me and she almost gloats about it to me and in some ways as horrible as it sounds I think she may be dramatizing her state with her anorexia because she has dramatized any illness in the past. But I can't just assume that and not support her because it could be true. She told me she saw a counselor so that relieves my stress a bit, but she told me not to say anything about her ED to my parents. I'm worried something will happen to her and it could've been stopped if I told my parents. But I also don't want to lose her trust and make her feel alone I think she may be able to come out of this if she keeps seeing the counselor and I support her, but what if that isn't enough? I'm very concerned any advice on what to do is greatly appreciated. We have a very strong close relationship I can't lose her.
