Hello- I see you are off line but will reply and you can respond if you have questions. From what you have written, I am concerned that there is something more that adolescent developmental issues going on and I would strongly suggest that she have a comprehensive medical and psychological evaluation to rule out any underlying bio-chemical or psychological
issues. That way everyone can be informed and reassured and she can receive treatment, if needed. I would start with her regular doctor and seek referral from him/her for psychological evaluation.
I wish you the best, Bill
