回复：behavior problem. Please help me!!!

You are right. Don't go to social worker/psychologist. They will make the situation worse because they don't know how to help you though they might want to help. Children's problems normally come from parents or close vicinity. I stongly recommend you to read a book "Child Dianetics" and take a short course called "How to Be a Successful Parent".

I personally have benefited from the book for my daughter.
