One of my close friends is anorexic. I am really worried about her. She is almost 13, 5 foot 3 inces tall, and only 85 pounds. She keeps getting thinner and thinner. At this rate, she could be in serious danger. I really want reach out and help her but I don't know how she'll react. I've tried telling her that I care about her and to please try to eat more. What else can I do?
