Anger is a normal healthy emotion. But when your angry outbursts cause disruptions in your life, become destructive, out of control, or begin to frighten you or those around you, it’s a good idea to ask for help to deal with your anger and aggression. Anger is felt in varying degrees, from mild irritation to blind fury. Like other emotions, such as fear or joy, it also has physical effects on the body, like increased blood pressure and heart rate. Antagonism can also be expressed as different types of anger, such as self-injury or passive-aggressiveness. Your temper might be roused by an external source, like a traffic jam or a coworker, or caused by worry or passive anger experienced during a previous trauma. It might also be triggered by an internal mental health struggle like depression or anxiety.
