Everyone has demons. Everybody has a mirror version of themselves that can take over in some situations. It's often challenging to accept this fact, especially when it revolves around aspects of your own psyche that you repress, or actively dislike.
I have anger management issues, I won't deny it. I got to the point where I gave my rage a name so that I could try to reason with it, to try to control it. I'll stress that I've only once lashed out physically at someone, and I was very young. Nobody was injured in the event, and I'd sooner cut off my arm than hit someone.
My methods of regulating my anger have had unusual and unexpected consequences though, and I think I'll always be learning about them. The trick will be in maintaining my objectivity, rather than crawling in to its cave and living with it.
