People handle anger in three ways: expressing, suppressing, and calming. The healthiest way to express it is to make yourself heard in an assertive (not aggressive) way without hurting anyone else. You also can try to calm, or control, your anger -- count to 10, take deep breaths, and let the emotion go away. But don’t suppress, or hide, it. That can turn those negative feelings inward and lead to high blood pressure or depression.
