anger comes from fear…
fear comes from lack of control, abuse…normally from early childhood.
you have to embrace your inner child. 
@Csummers said something beautiful about that on a post of mine …she is very wise.
take care 
We used to say in recovery meetings that there is no right or wrong in trivial matters…
… Which basically means that most things that make us irritated are of no significance…
… Someone can disrespect us… No big deal
… Something can break… No big deal
Only big things that happen in life are stuff like deaths, births, divorces, wars, natural disasters but those are relatively infrequent.
That’s not to say there aren’t disappointments…they occur every 10 seconds or so… Unrelenting… It’s just that we have this belief that life is supposed to be comfortable when it can never be totally so.
Anger is holding a belief that a person or situation is ethically wrong. It’s a tough habit to control but you can drop beliefs with practice.
Covers the cognitive leg of the triangle. The mindfulness meditation thing often handles the other two (affective/emotional and behavioral).
In the past I have had an opposite problem, when I should have become angry I did not become. Being angry is just one emotion and being nonemotional one may forget how to be angry.
You are red.
I am blue.
I get raged sometimes, though its mostly my fault. I let small things eat at me and bug me without talking to the people causing them because I don’t like confrontation or attention. They get worse and worse until it’s all I can focus on and I just snap.
Though I don’t get violent, I just blow up and yell. I get ideas that can be considered assault, yet harmless though. Like dumping a bucket of water on the person causing the problems, destroying their property that they use in causing the annoyance, or making violent (but empty) threats.
Fortunately I’ve only had the cops called on me once.
When I was younger I was very destructive with my anger though. I did a lot of stuff I regret. When I learned to meditate, I gained a lot more control over my anger.
