...In response to seeing that I'm in my normal weight range:

"Well, at least it's not that bad."

It doesn't matter how sick I am, how many times I B/P, how desperate I am for help; as long as I'm in my healthy weight range everything is fine. After hearing that, I just want to show everyone how self-destructive I can be.

OR

"You don't look like you have an eating disorder."

Because that sounds an awful lot like: "You're fat."
