Child is anorexic and hospital won't do anything?

You should withdraw her from the hospital asap and talk with her one on one in her room. Let her know that you love her. Write a letter explaining how much you love her and how badly you wish you two could go back to the way things were. Seal the letter and leave it with her, after your talk, with a sharpened letter opener. Tell her "whatever happens happens" and walk away. Sometimes they're better off
