If you think your daughter is hurting herself, the very first thing you need to do is get a health professional involved. Unexplained weight loss, sudden changes in behavior, unexplained major mood changes and weight loss are all major red flags. Keep a detailed record of what you see your daughter eating over the course of a week, as well as any behavior that concerns you. Then, take your notes to your family doctor and get his or her advice.
If your daughter is indeed harming herself, she needs help right now. Unfortunately, as a parent, you're not the right person for the job. You’re too emotionally close to the issue and it will be very difficult for you to maintain an objective point of view. Start with your daughter’s pediatrician, who will refer you to an appropriate specialist if necessary.
