Answer:
My biggest concern for Margaret is that she may have an eating disorder. Eating disorders are serious and I am afraid that she will get too skinny which can be a big medical problem. I would voice my concerns to Margret and I would also try to help build her self esteem. Also, I would try to get to the root of the issue, why is she feeling so low about herself? What caused this to happen so suddenly? If I can find out the reason then we can get help. However if she does not want your help and it continues to get worse I would talk to a counselor or her parents because they may not be aware what is going on.
