Sorry wife can into the room and I posted quickly.
My wife said for years that I should go to Anger Management. I had an ego and said there's nothing wrong with me. This spring I went for 12 sessions, an insurance program allowing 12 sessions a year. Interesting thing I got from it is that mindfulness is an important tool in managing anger. Stepping outside the anger to manage the emotion. Learning the signs of anger to see it coming. Frustration is a low rung on the ladder of anger. Another thing is what I thought was anger when I went "off" is now what I would consider rage.
I now reject the indulgence of anger. There are much better ways to solve problems then behaving like a child.
