My first thought also was bipolar because hyper-sexuality is a symptom of that. IF it is bipolar, it could have manifested itself after the divorce because often difficult situations which effect stress levels will allow the disease to read its ugly head! Our 15 y/o daughter was diagnosed with it last spring and it became obvious to us that something was wrong 3 years prior to that, shortly after I was diagnosed with breast cancer. Because your daughter was sexually abused as a young child and because of the divorce she also be dealing with PTSD, or a combination of bipolar and PTSD. I agree that she needs to see a psychiatrist for an full evaluation. By the way, our daughter was also 11 when symptoms started to appear.
