Welcome to Psych Central, crystalstar.
You mentioned living with a brain injury. I've often thought, given what we know about concussions nowadays, that I must have some brain damage as well although mine would be something that developed over a period of years rather than an injury that occurred in a single incident. For almost all of my life I've had difficulty with anger management. And I suspect the two are related. Anyway... I hope you find PC to be of benefit.
