I can relate. On days where you feel you have severe difficulties controlling your response to anger, I find it is best to avoid people that day to regroup and de-escalate. Sometimes I put my phone on silent, since I noticed sometimes certain people who contact me are triggers (especially after a fight or something that irritates me). It also deters me from taking anger out on others accidentally when I do this.

Have a day dedicated to you: your favorite food if you'd like, put on some music, ,make your room especially comfy, curl up and watch a movie that either releases some of your anger or something that makes you laugh and temporarily cool off.

Focusing on anger can inflate it even more so that it takes total control over you and your behavior, so distractions are a step towards letting go. You cannot control others or events around you, but you can control your response if you give yourself some space and time away from possible triggers.

I am by no means an expert. I struggle, but giving myself a "me day" is something I find to be helpful when possible.
