You call yourself a high achiever, a hard driver, determined, and all these traits are fine. The only question is why?
I was always an achiever to please my parents, to have something to brag, and to use to look down on someone. That I am intelligent, that I am greater than others.
I used ED to lose weight drastically to prove and show that I am more beautiful than others. I purge because I feel guilty for eating a lot, eating more than I can afford.
