Dear editor,

　　I’m a middle school student. I once had a very happy family, but everything has changed because of my father.

　　He used to be a very good doctor and was often praised by his patients. He took good care of the family and shared the

　　housework with my mother everyday.

　　However, he is now quite a different person. He plays mahjong all night and often quarrels with my mother. I just can’t concentrate on my studies and my grades are coming down. I’m very much worried and I’m afraid it will destroy my family as well as my father

　　Could you help me what to do? I’m looking forward to your reply. Thank you very much.
