My daughter is 14 years old and studying in class 9. She has a problem of concentration and that effects her studies. As she is not good in her studies, she avoids studying. On being told to study or being reprimanded for not doing well in studies, she reacts very rudely and violently. We try to handle the situation cautiously and calmly but sometimes it goes out if hand as she continuously says things to hurt her mother. She even goes on to say that she wants to commit suicide. In general her nature is soft and she repents for her behaviour later on. But she says she is unable to control herself. Her behaviour at school is very good and she is known as a soft spoken child. But overall her studies and her erratic behaviour is causing us a concern. Pl help..
