I have had a BIG problem with anger (including legal, unfortunately). Did you have a frontal injury? Most TBI-related anger is frontal damage in nature.

The reason is that the forntal lobes of the brain are where anger is normally controlled (along with most other primitive emotions). When this Executive Function is impaired, raw emotions can run unchecked.

In answer to your question, I have found the biggest help is 1. Not to blame or judge yourself for the outbursts, and 2. Let the anger run its course (obviously without resorting to physical expression.) Just go off by yourself, have a nice mad, then return to "normal" duty when the demon dies of natural causes. It really does work!

Best of luck to you.
