Some tips for dealing with anger from the American Psychological Association:

"Breathe deeply, from your diaphragm; breathing from your chest won't relax you. Slowly repeat a calm word or phrase such as "relax" or "take it easy." Use imagery.

Change the way you think. When you're angry, your thinking can become exaggerated. Try replacing these thoughts with more rational ones."
