The best way to handle anger
I think the best way to handle anger is to stick to this three-step: try to go back to calm, analyse the problem which made you angry, and try to find a solution.
For going back to calm you should leave the situation that made you angry. Send your apologies and ask for a permission to go out for a minute. You can just say that you are feeling sick and you need to go to the toilet. During that time you should check out your own state: how is your breath? are your muscles tense? Do you need to cry or to shout? etc. If you are able to go out for a walk or to wait twenty-four hours before going back to that situation, all the best. That will allow you to leave the problem behind for a while.
Only when you are calm again you can go to the next step, which is analysing the problem. You ought try to remember exactly what happened. Try to recall as much details as you can. For example try to remember how was the room or the place where it happened, which clothes had the people on, etc. This is a trick for being objective. After becoming objective about what happened try to understand why that situation annoys you so much.
Finally, you will be able to turn to the next step: finding the solution. The understanding of the problem will be the key for finding a solution. Usually, only speaking to the other people involved leads to a way out. During this conversation you will need to express your feelings and thoughts and being able to understand the point of the other person. Then you might be able to come up to a consensus.
