My therapist told me I had an eating disorder when I was at a normal (but curvy) weight (145 or so ) . I disagreed because I wasn't "skinny.' I said I won't go lower than 130lbs. If I was 120lbs, I told her, then I would know I have a problem. I got down to 116. Did I think that I had a problem? heck no! I wanted to go lower! That's what an eating disorder does to you. You don't want to stop. You can't stop. Until you get really, really sick, or die.
You need to get some help.
