Sure. I think that the new kid on the block is a bully,and he is bothering your son,and your son is angry. Your son does not know what to do with that anger. Buy him a punching bag. I had one when I was a teenager. It did wonders for me. Maybe you can call his school principle,and he might be able to investigate the situation in secret. Your son is probably afraid to say anything at school for fear of being called a tattle tail. That would be a pile of shame on a teenager. I believe anger can send obsessions,and compulsions into a vicious cycle. He may be sensitive,and these thoughts of being bullied may be going around,and around in his head. This could be tormenting him. People without OCD can release these thoughts,but people with OCD may not be able to. That hurting cycle of thoughts will probably be replaced with the next hurting cycle of thoughts. Does he have any hobbies? Find out what he likes,and provide the resources for him to explore,create,and build upon.
