Sofs is the answer I prefer here. If anger is so intense that you feel you might react physically - head outside and start walking. Let off steam. But note the mind chatter. All the self-talk about why you're angry will only add fuel to the flames.
Once you've calmed down a bit you can then examine why you were angry. After all, you felt the emotion that you felt, not the other person. It's your problem. They probably only triggered it. They perhaps 'bruised your ego,' or 'insulted your self-image.'
This self-image which flies into a temper, or gets hurt in an emotional way is not the real you. It is the made up you- made up by your identification with your thoughts and the feelings which accompany them. Once you truly understand this, you're on your way to getting rid of them.
