Let me suggest that you read the book "Eat Right For Your Type" by Dr. Peter J. D'Adamo - also I would recommend that you put your daughter on some good vitamins with All the B's - and extra iron - hormone's can deplete the body of the B6 and B12 vitamins and iron which can keep the body in a depressive state - talk to your Dr. and see if she can suggest a good homeopath or naturopath who can help you with nutritional and supplemental information. The book can help answer some questions about your daughters' "dis-order" that is going on in her life at this time. She is going through lot's of changes and there may be some underlying emotional stuff also. Just be open to the alternative ideas - there are many answers there. Good Luck!
