this is all still your eating disorder at play--I don't think there is a single ED person here who doesn't think they are sick enough and I need to prove I've really got this thing...you don't have to prove it, you are worthy of the help you are getting. You don't have to be a textbook anything, just a human who is really struggling with her life and is using food and her body to express it.

Tell your team, if they truly understand EDs they will understand this distorted thinking and help you work through it, if not, I'd find a new IP program.
