My daughter, 17, has complete personality changes when her number is really high (350-500). Today was the worst ever, with verbal abuse, cursing, and an unbelievable rage. I am so scared - she is violent with me and today our animals as well. She called the police herself today because she was so afraid of her behavior and ended up in the hospital until her numbers came down. She then apoligizes and acts as though nothing has happened. I have tried researching this and have found no real insights/information. She has adimitted that she is once again keeping her numbers on the high side to try to lose weight. I am at wits end ... I am worried for her and our entire family. Has anyone ever experienced anything like this? Advice?
