VERY LAST level 1 piece in the M.O.M collection! Anger is an emotion characterized by antagonism toward someone or something you feel has deliberately done you wrong. Anger can be a good thing. It can give you a way to express negative feelings, for example, or motivate you to find solutions to problems. But excessive anger can cause problems. Stress, anxiety, depression, and anger are often related. Stress and anxiety can cause anger, which can then further increase anxiety, depression, and stress. Learning ways to manage these feelings can also help to minimize anger.
