Asperger's and Anorexia

My daughter is 18. She has been suffering with anorexia and body dysmorphia since she was 13. Academically she is exceptionally able but has always struggled socially. She has only recently, in the last year, had the Asperger's diagnosis. She is devastated about  and cannot accept it. Her meltdowns have increased and her eating has severely deteriorated. She is refusing to receive any support. Is anybody else experiencing a similar situation?
