At present, it seems that your child has no obvious specific mental illness, but many psychological problems, such as rebellious psychology, internet addiction, family problems, etc., which are also related to his personality and family life, school life and social life environment. As a parent, you should first solve the relationship between your child and you, which is the premise of dealing with your child's problems. Secondly, we should understand children's school life and social relations and find a breakthrough. In order to help children, you should know more about parenting education, consult psychological counseling institutions and other related professionals, and consult more about the psychological problems of children and adolescents.

In view of this child's many problems, I can't make it clear here. I recommend some related books, master some knowledge and find some methods:
