Hello Cheese123: I see this is your first post here on PC. So... welcome to PsychCentral… from the Skeezyks! May the time you spend here be of benefit.

Unlike you, I have pretty-much always been an angry person. What I strive to do is to use a Buddhist practice which is referred to as "compassionate abiding". Compassionate abiding involves simply allowing the intrusive thought (anger in this instance) to come forward... breathing into it... perhaps even smiling to it. Sometimes I will even place my hand over my heart as a sign of lovingkindness & compassion for it. After a few breaths, I then drop the "story line" & simply continue to stay with the underlying emotion... be it fear, anxiety, grief or whatever.

Two things happen when we employ this practice. First, very gradually over time, the strength & frequency of intrusive thoughts wanes. But second, & perhaps more important, is that we learn we can stay with difficult thoughts & emotions without losing our balance... our equanimity. Here is a link to a mental-health-oriented description of the practice of compassionate abiding:
