Extractions: I would say that there is some mood issues that happen when puberty hits. It could take on a variety of forms. As I read your issue I was wondering if something has happened with your son that he has not told you about. Has there been a move, death divorce or something else that you may not see as significant, but he does. It seems that while your son may be sensative it may be important to teach him how to be assertive. A drama class may or may not help with that. Considering a class where physical excersize and training in assertiveness may also be on option. Karate or some type of martial arts where they miz the physical with the emotional may be beneficial. Going to a therapist may also be beneficial. Finding a person he can talk with knowing that what he shares won't be shared may be important to him.
