I assume you are in some sort of treatment center. Try to trust that the people your interact with are professionals trained to help people with anorexia and that it would be wise to head their advice. Perhaps you can write letters/make phone calls to friends or family members for support if you feel like you aren't getting any where you are. Sometimes it helps to hear it from people you love and trust. I know recovery seems insane to you right now, but it won't always. Just try to trust others.
