Anger can cause serious physical health problems like ulcers and heart disease. It can also make you act in ways that cause you to lose your job, or friends or break up your marriage. You can deal with anger as it happens and you can change your approach to life.
Short terms solutions to anger:
Admit that you are angry. By denying feelings of anger they will not go away, instead they will keep reappearing in inappropriate ways.
Try not to over-react. Think about whether the situation is really as bad as it seems. How would you feel if you saw someone reacting as you have to this situation.
Force your attention onto a more pleasant thought, a happy vacation for example, rather than the line up or traffic or whatever has you angry.
Identify the source of your anger. Is it the actions or words of another person that is hurting you? If so, try to deal with that person in a peaceful, productive way to get them to understand why you are angry.
Listen carefully, without interrupting the other person, so you can understand what the person is trying to explain.
