Kim, this may not be the option you want to hear, but it sounds to me like a cry for attention. That's why I stopped eating for four years - I just wanted my parents to notice something, anything about me. Of course they did (just not the fact that I didn't eat so that was a waste of time), I just felt they didn't, you know what teenagers are like! She's not depressed and she's normal apart from not eating... it sounds like she just wants more attention and doesn't know how to ask for it.
