Eating disorders.....
Eating disorders don't just happen...once you know it's an eating disorder you need to work on it as would any addiction....but your friend need to seek help...the issue is not staying thin...it's a poor self image. My Bulimia started in High school and I finally told my DR when I was 35 at the time...Beaumont has a very good eating disorder clinic.
