I have been looking at some guided imagery CD's. There is one for children to help them handle anger, the confusion of growing up, the frustration of not having their desires met immediately and many of the other growing pains experienced by all children.

I used guided imagery to help with some health issues and it was very effective. I lsitened to the tape for about 1/2 hour a day. It not only made me feel better but it relaxed me and made me feel at peace. I'm not saying it will work for your son but it can't hurt. Give it a try.
