Anger can be described as a secondary emotion as it covers up a primary deep-rooted emotion we are feeling. The primary emotion is the one we feel just before the anger takes over as we always feel something else first before we get angry.
Typically, one of the primary emotions, like fear or sadness, can be found underneath the anger. Fear includes things like anxiety and worry, and sadness comes from the experience of loss, disappointment or discouragement.
Anger can also be a primary emotion that tends to be repressed in most people. It is an emotion, like the experience of anxiety, about which we often feel shame, due to our negative views of anger. … In this respect, shame, fear or anxiety can mask anger or rage.
Some common roots of anger include fear, pain, and frustration. For example, some people become angry as a fearful reaction to uncertainty which is so common nowadays, to fear of losing a loved one, a job, or to fear of failure. Others become angry when they are hurt in relationships or are caused pain by close friends or work colleagues.
