"Anger is a strong feeling of displeasure. It is often a reaction to stress, failure, or injustice. Anger can range from mild irritation to full-blown rage. It is normal to experience anger. At times, anger is the appropriate response to the actions of others. When managed correctly and kept in check, anger can be an important ally to a healthy adult. But anger has risks, perhaps more than any other emotion. It can alienate people from others and lead individuals to do things they later regret. People who have lasting, extreme anger may find it helpful to explore its causes with a therapist."
