@Scrbblchick -- I know, isn't it strange that anorexia is so very difficult to treat? The addiction is the same as with alcoholism, but it just involves not eating. The mental symptoms are largely the same. Every drunk thinks they can put it down after "just one more drink," while every anorexic says she can start eating after losing "just one more pound."
I don't think the media helps one bit, either. I think girls are bombarded with these impossible, unattainable images that are usually photoshopped, and they start thinking that's the right way to be, so instead of looking for a healthy body, they strive for an extra thin body, which may hurt them badly in the long run.
