My teenage son is angry, but he is oblivious to this. He does get in trouble in school and with peers, as he bullies them. How can I convince him that he is angry and needs to confront this for his own sake and for the sake of those whom he bullies in school?
A key to breaking the defense mechanism of suppression or repression of the anger is to have a quiet conversation with him in which you go over some of the specific consequences of his anger. Help him to see, in the safety of his relationship with you, that he is getting in trouble in school and is bullying others, making them miserable. Ask him, then, if there is anything inside of him, such as intense anger, that is causing these problems. Eventually, these consequences will have him suffer enough so that he becomes aware of the source of his suffering, which is his anger. From there, you should see if his anger is caused by unjust treatment toward him, in which case his practicing forgiving (specifically toward those who hurt him) may lower that anger.
