What is their rationale? Do you do excessive fasting or purging?

I had this happen to me when I sought help years ago from my university health / counseling center. They determined my case was "too severe" for them, but they could refer me to outside psychologists. I was young and inexperienced, I didn't have a car, how was I supposed to deal with that?

More recently, I had a therapist dump me by assuming I was being insufficiently compliant, after I missed two appointments and failed to gain weight fast enough... she also claimed that "most clinicians" would refuse to treat someone at a BMI <16 (or 16.5? can't remember) on an outpatient basis. Like, wow OK then.
