Anger
What is anger? It is suggested that real anger is an addiction. People need a fix of anger in the same way that others need a fix of alcohol, drugs or caffeine.
A more general explanation of anger is that it is a ‘mask’ for fear, emotional pain or emotional hurt. Ponder over that should you consider you have an anger trigger.
I used to have feelings of anger and can relate to the mask explanation.
I rarely become angry. It is so debilitating. As quickly as possible I quieten myself. If necessary I will ‘tap’. I detest the feeling of not caring what happens next and being potentially out of control. No one will benefit. Least of all me. I cannot function properly when angry. Who can? There is no excuse for any behaviour resulting from a fit of anger.
I could labour this but to me the explanation given covers all bases.
