There is a lot of info in the information section on anger management. Anger is very common.
I went through a phase my doctor was happy I was getting it out but not those around me! Had to learn those I surround myself were not the root causes and to try to learn not to bottle it up. When I hold it in I get huge panic attacks.
OK sometimes my teens did/do really stupid shit that piss me off and I should be... But adults that think they can yell at me, I have nothing to do with. That much I have control over. As in other's actions if they were not intentional I had to learn to center myself and remember what is done is done and to look for ways to prevent those things happening again rather than blowing a gasket.
