Getting to the source of the anger can help lead you towards resolving it.
Are you able to link the anger building at a particular time in your life??
How were feelings of anger dealt with in your house growing up? Did your parents model healthy ways to express anger and methods of dealing with frustrations? There can be many factors coming into play. It would probably be much more productive to explore this with a therapist who can help you track your history so that you can work on finding the appropriate resolutions. For instance, if you’re in a bad marriage, you may not be able to work through your feelings of anger while you choose to live there. If you’re at a job where your supervisor is rude and disrespectful on a daily basis, it’s unlikely you’ll feel better while there (although you can learn techniques to temper your response to your anger), if it’s biochemically driven, you might find yourself a whole lot happier and more relaxed by taking something to calm you down.
