It is a signal that we are being hurt, our rights are being violated, or our wants or needs are not being met. There is nothing wrong with feeling angry. How we express anger is important.
People often bottle up their anger to the point of exploding or becoming depressed.
They need to learn how to handle that anger in constructive ways so they won't feel helpless and powerless. It's important to recognize anger in yourself and others, identify the cause, and make a plan to express the anger instead of bottling it up. Determine what options will resolve the problem and take positive steps. Take time to calm down. Physical activity, rest, and relaxation, or plowing into a project can diffuse anger.
