Try repeating a mantra;
If you are one who listens to your inner voice of yourself or finds it good to speak to yourself, try finding a word or a phrase that has high potency in calming you down whenever you get angry. It could be phrases such as; “it will be fine” “relax and take it easy”, “ignore this one. It’s not worth it”, or “not today”.
