I replied to this in both forums. I just wanted to make sure you saw it. I think I crossposted with the Moderator.
Anyhow here is my reply..........I'm not one to diagnose things as illnesses very often but this one I read and think it could be either a low level bi-polar disorder or turrets. It could be an unattended inferiority complex. It could be A LOT of things really. I would maybe invite her to family counseling between the both of you at the very least. It would get her in front of a professional for observational diagnosis purposes and offer her an outlet for her anger frustrations and aggressions. Sending family healing vibes your way.
