It has been argued many a time whether ot not anorexia is truly a disease, or if it is simply
a choice. Here's my theory:
Anorexia begins with a simple concious choice. "I'm not going to eat." Eventually this choice,
becomes an obsession. It is when the choice becomes an obsession that it become anorexia nervosa - a disorder.
Anorexia is about control. If you have control, you don't have a disorder.
