Dd16 makes all of our lives a complete and utter misery. She is nasty, violent and abusive toward everyon from her three year old brother who she kicks, calls names, her sister who she pushes and insults to me and dh who are sworn at, threatened with knives and abused. She ruins every holiday, every birthday, every occasion. She has no friends or social life so is at home all the time when not at school. The only way I am able to manage her behaviour is making her stay in her room and away from everyone else. Please believe me when I say we have tried everything. Gp not interested and only gave us details of counsellors for anger therapy etc which dd point blank refused to go to. She has been like this all her life and I can honestly say the misery and heartache she has caused me far outweighs any happiness. I have tried doing things with her alone, giving her individual attention, talking to her, she takes up more if my time and energy than the others. I need her to go when she is 18. I need her to go for all of our sakes. The other two cannot grow up living in fear with her constant abuse in their ears. I feel as if I am serving a prison sentence. She has no ambition and just laughs and says she's staying here forever. I feel trapped in an abusive relationship as I don't know how I can make her go, I don't know if I could bring myself to throw her out. Please don't post to tell me all the things I have done wrong, I have read every book, tried every approach, nothing changes.
