I think Mindfulness is a good way to deal with emotions that take over our thinking. When I started to CONSCIOUSLY use my pre frontal cortex.....
the rational , thinking , part of my brain , it got better. I hardly ever used that
part of my brain , only the emotional part. Also trying to get to the root of your anger may help. It’s most likely that a past hurt , something you couldn’t do anything about , is the root of your present anger. Just some thoughts........
good luck to you. Find someone, ( therapist, friend , ) that you can confide in.
