Any type of violent act is not right, except when you defend yourself from violent acts; otherwise, even if you were in a purely verbal situation and you were in the right, it still didn't give you the right to be violent towards others. As a person who also suffered from anger issues, I can understand how it feels to not be able to control yourself when the emotions are high. Whenever I got angry, I mostly couldn't control my words, and because I was still aware of myself, I couldn't hurt others, so I started to hurt myself, like pulling my hair, slamming my head, or stifling myself, and I would cry. I also sometimes hurt my pets (like soft punch them or slap them, not like make them bleed or smth)
Recently, it has gotten better, and I mostly just raise my voice when I get angry without using any physical acts. I will try to stop myself, breathe, and try to think if it is worth it to be angry with that specific person or issue, or is it worth damaging my health over something that eventually will just bring me misery and nothing more? I didn't go to any help and usually try to calm down all on my own; if you want, you can try it sometimes by yourself; try to breathe, calm down, and tell yourself that you will be okay.
It works for me and I hope it will work for you too, wish you the best
