Based on what I hear,I think that he may have a bullie problem. Somebody is bothering him maybe at school.

Does he have any learning disabilities? These things may be all pinned up inside plus hormones,and the other aggrivations he is displaying.

It sounds like he is really angery,and it's pinned up in him. For your own good please stay away from him at this time. My dad had a terrible temper,and when I was around him when I was growing up,when he'd blow up with his temper,I caught the shrapnel.

Please be careful around him at this time.

Is there a guidence counsellor that he can talk to at school,or somebody who he trusts? BF
