I also had a rage-aholic father who suppressed his frustration and anger from the business world for weeks or months before releasing it from time to time by beating my siblings and myself.

Consequently I had suppressed rage that I took out on myself for a long time (became a raging drug addict). Fortunately, I eventually found my way into a few years of mens groups and then many emotional release intensives. In the intensives, we did give expression to our negative emotions, but in a very controlled, contained, and safe atmosphere.

In one intensive it was jaw droppingly amazing to see a tiny German woman, who had been repeatedly raped by her grandfather from the age of 2 onwards after the War, push back and almost bowl over a group of 10 volunteers surrounding her with pillows as she let go.

I don't think that I bottle up negative emotion so much any more. I also don't think that I give (unconscious) expression to it. Or maybe I'm just getting old :-)
