My daughter is 11 years old and is a very angry child. She has been this way for at least 3 years now, but it has really progressed in the last year. She can be the sweetest child when she wants but then turns into this evil person. For example, just last night I was going out and she was had to stay home with her 19 year old sister and s16 year old sister, she became so sngry when she heard me on the phone, that she just burst into tears screaming and yelling going into her room, saying that she hates me, hates my house and wants to live somewhere else. I hear this all the time. She then called me a stupid *****, and tried to kick her bedroom window out.I got a belt to disipline her and she tried several times to hit me, and kept pushing me out her way. She was trying to call the poilice because I hit her. I go through this with her at least twice a week. She is always mad about something, She cusses at my two there daughters as well as the kids on our street. She has the same problems at school. No one ever wants her around or to go anywhere because of her behavior, but then she the next day can come and she is like a totally different person. I need help because I am so scared that I will hurt her with me getting upset, and tired of her acting out. She needs help badly. We are sometimes afraid to goto bed because she will be up watching us.
