Re: Help Please Help :'[
Sounds like an eating disorder. My friend developed one about that age. Every time we went to lunch at school she would just sit there and complain that she wasn't hungry. We all just kind of "brushed it off" because none of us realized what was really going on. She lost so much weight so quickly, ended up in the hospital, and regrets missing a whole year of school.
I think it's most important to listen to your daughter and find out what she needs (mentally). There is definitely something bothering her that she is having a hard time dealing with.
Take her to a doctor. Be supportive, but don't be a "friend", (like I was to my friend suffering). I wish I would have helped her the moment I noticed her behavior wasn't normal, even though I had no idea what anorexia was.
