Welcome to SR. When I was in early sobriety I had a lot of anger. I still explode once in a while. If I find myself ready to blow I take deep rhythmic breaths and relax my shoulders. I take a quick walk. I write it out or by venting to an understanding friend.
Most everyone has certain routines in their life. Distrupting my routine sometimes throws me off and I get angry. I know enough now To predict when it will happen and how to manage. What can I do in advance to keep things on track.
Walking away helps. Not rising to the bait is crucial. I also had to accept my role in things. What did I contribute? What did I have control over and what did I have to accept? Saying the serenity prayer helped too.
Good luck. Keep posting.
