Whether you know you have an eating disorder or are thinking you might have one, a good idea is to get an assessment from a mental health professional who specializes in eating disorders.  A good assessment should take at least three sessions (in my professional opinion) so that the therapist can get as full of a picture as possible when trying to help you understand yourself and your eating disorder better.
