Like Bipolar1Disorder, I find that my meds help. What is the first things that convinced me that the bipolar diagnosis was correct was that the addition of the mood leveler pretty much wiped out the anger that followed me like a persistent shadow.

In therapy, I went back to my meditation and yoga practice and found coping mechanisms there--simple things like breathing. That helps me.

Also, realizing the anger isn't about the immediate trigger that it seems to be about also helps--the problem always goes a lot deeper. I developed a little mental exercise: I shake the anger into a virtual bag and tie it up and bring it to therapy. The very act makes me kind of chuckle, and that gets rid of the immediate feeling of anger.
