I have a daughter aged about 15 years, she is very good in study but she has a major problem. She always fights with her mother even she abuses her and slaps her .during time she uses to say absurd language. Although she needs her mother the most. Other wise she is very affectionate. In her childhood when she was 07 yrs she got same problem. She has a very good behavior in her school mate and other relatives. Please suggest me what to do.

Adolescence is an age of turmoil. Some aggressiveness and argumentativeness is common. This is more common with mother as she is interacting more then father or anyone else. Only two things which I consider abnormal here is slapping and using absurd language. This raises suspicion of developing psychosis. You should consult Psychiatrist near by.
