Anger Management Support Group
Anger management commonly refers to therapeutic techniques by which someone with excessive or uncontrollable anger can control or reduce their emotions. Typical examples include the use of deep breathing and meditation as a means to relaxation. Psychologists recommend a balanced approach, which both controls the emotion and allows it to express itself in a healthy way.
You were in a messed up relationship, you had every right to be angry. It doesn't appear that you went out of your way to hurt her but only you know the truth in that.
It's hard to identify anger in someone based off one scenario.
My STBEW convinced me that I have an anger issue - I went to some AM classes - check meetup.com they should have some low cost or free classes in your area.
The classes helped me identify anger and how I deal with it. They definitely shed some light on anger for me. I walked away knowing I don't have have an anger management issue because everyone has anger its how you manage it that is the issue.
Best of luck to you.
