My daughter has had three bouts with anorexia. Pushing her to eat willnot solve the problem. Anorexia in a mental illness that needs professional help. If that person does not want or think they need help. Don't force the subject. Instead focuss your attention on positive things that they are doing. Don't focus on looks or food it will only make things worse. Help build that persons self image with the great and wonderful things that they do for others or for you. Take all attention off of looks and food.
