How old is your child? What are the problems you are having?
Having sought help for myself and my child, I don't think my child was scarred. He was only 3, though, and mostly it was dh and I that got help from a child psychologist. It did help, but looking back, I would focus more on myself and my reactions to his behavior. That's just me and my situation. Thats what is helping me now, to be a better parent to all 3 of my kids.
We knew it was time to get help because what we were doing wasn't working, we were very, very frustrated and we felt that the way we were dealing with it was having a negative effect on our ds. Also, he was having difficulties everywhere: home, preschool, play group, any social situation, basically.
