I am new to this page so pardon me if i do anything wrong. For the past 2 to 3 years my youngest daughter has been destroying my family. I thought that my middle daughter was tricky as she is exceptionally sensitive but my youngest is beyond anything I know. She has been kicked out of 3 schools now, one being private. she is rude and abusive to teachers, walks out of school and goes missing. She lies, steals, is violent to myself and property. I have been forced to call social services for help but got none as we are a fairly wealthy family. The police have been called to the house on many an occasion, and she has even been taken off in an abulance for an overnight stay at the local hospital as she said she wanted to kill herself. She was assesed at the hospital and they said it was behavioral not mental health. My eldest Daughter has left home due to her behavior and the stress that she causes, and my middle daughter has attempted to kill herself due to stress of her younger sister. Its that bad. She intimates and bullies everybody if she does not get her own way,I have been forced to put locks on all doors in the house except the kitchen and lounge due to her stealing. She goes missing for days at a time, I have given up calling the police as they have better things to do than chase her around. I have tried, grounding her, taking away privilages, councelling, anger management, family mentoring, ignoring, talking, rewarding, Shouting,repeating rules etc. I have read book after book. I am exhusted. I cant work out what we have done wrong. She has had a lovely upbringing, taught right from wrong, respect, everything. She was such a lovely beautiful girl and still is to look at but it is like she has been taken over by a demon that i cant get through To. I am so worried as this is her GCSE year and she is now having to attend a PRU and god knows what type of friends she will make there.I dont think she will obtain any GCSE'S and then what? I know that for teenagers friends are important but hers all seem to all have issues and sometimes I wonder if she is just doing this to fit in. I have read messages on her laptop that she has sent to friends saying how horrible i am and that I hit her (i dont and in all honesty if i did i am not sure if i would be able to stop) Her new thing is not eating or prending not to, just to worry me more. Its ripping my family apart, My middle daughter spent 3 days in hospital a few weeks ago and the 15 yr old went missing at the same time, maybe because the attention was not on her, I found her and asked her just to behave and not throw a tantrum for a few days so that my middle daughter had some peace, this was like red rag to a bull and she became so abusive and load that i had to get her to go and stay with a friend. So in many ways she got what she wanted. she bullies the whole family. I have been with my partner for 8 yrs and we have all always got on, but he is now having to step in and that is causing more issues with her. Her father is no good at all and blames me for everything and has in the past gas lighted me in the past to a massive extent and still tries. can this be genetic? as the lies and warped logic are just the same from both of them. I am sorry if this is a ramble.
