As a general statement, recurrent head trauma is a bad thing. Boxers, football players, etc can experience long term progressive damage from concussive injuries to the head. A psychiatrist is a good first stop, especially one with a background in neurology. Rage with self injury may be related to other physical conditions.

Hi
You are in need of urgent attention by a psychiatrist.Make a casebook of all yoru experiences,positive and negative in writing,and take it alongwith you.It will help you explain yoru condition to the psycho.Go to the doc with coolhead.A non-professional like me cant give you advise.You must visit the psychiatrist.
