我很理解你，孩子和孩子不同，有的的确比较难弄，

Some of them are wired like that. As parents, we have no choice but accept
them as who they are. So please drop your negative feelings about him.
That will help him relieve negative feelings about himself.

Going to a child psychologist does not necessarily mean taking medicine.
They will teach your son some strategies of how to manage his emotions,
especially at school. It doesn't hurt to give it a try.
