I knew a girl in school who was incredibly skinny. I don't know howmuch she weighed, but I thought she had anorexia. Anyway, my cousin was like best friends with her and said it was some other problem..I don't remember what it's called, but it's nothing to do with her not eating. Could it be that?

As for anorexia and bulimia, I unfortantly had a front row seat in seeing how bad it can be. My sister had and I guess is still struggling with it a little bit. She seems to pretty much be over it but it's hard. She is around 5'6 - 5'8 at one point she weight 70 pounds. So yeah, she was in the hospital with feeding tubes almost at the point where should was very close to death. If you suspect something, I wouldn't leave it. There definitally is a time when it's 'too late'. However, anorexia people tend to be very defensive if you say stuff like that to them. I'm notsure how you would go about it, but I think if that's what it is, something should be done. Does she go to the bathroom after she eats?
