Frustration, annoyance and anger are all normal, healthy emotions. Everyone experiences them from time to time. Anger can motivate people to get involved in important causes, or to stand up for themselves. Anger also alerts and prepares the body to react to potential danger. In other words, anger can be a good thing! What's not good is when people express anger in violent outbursts, or when they spend a great deal of time simmering with rage, or when they keep discontent bottled inside, failing to express it at all. People who have trouble displaying anger in a healthy way may experience a host of problems. Physically, they're more prone to headaches, high blood pressure and digestive upset. Emotionally, chronic anger can cause clinical depression or anxiety. How do you know if your anger is run-of-the-mill and healthy, or out-of-control and harmful? Angry feelings are a problem if they regularly cause you to react in ways that you regret, whether that's physically hurting those around you, or emotionally disrupting your relationships. If people appear afraid of your reactions, if you have regular run-ins with the law, or if you attempt to intimidate others with your anger, you likely need help managing your emotions. The bottom line is this: if you have a problem with anger, you probably instinctively know it. When that's the case, it's important to see a mental health professional to learn healthy ways to manage your anger.
