I recently read "Diary of an Exercise Addict" by Peach Friedman. It's the documentation of her slide into exercise bulimia. She tells how exercise became her crutch for coping with life. She tells of binge eating and purging with workouts that became increasingly long and painful, until she was a shell of her old self.

Exercise bulimia is really hard disorder to deal with, and probably easy to develop because we are all taught that we should be exercising more. Eventually, more can be too much, and before you know it, you have an eating disorder.

I think this is important reading for any athletic person. The line between fit and this disease is fine, and you may not know you are suffering from this until you've already done great damage to your body and your life.
