Anger and what to do???

What do I do with this emotion?  I am afraid of getting out of control.  I do not think that it is good to have this feeling.
So what to do to express this emotion in a healthy way?  First of all try to cool down.  If you are fuming, take a break.  The brain has been hijacked and it is impossible to think clearly.  Stop, take a breathe, drink water, go for a walk.  Do what helps you to regain your composure.
Can there be different parts of this anger?  Are you sad or hurt?  You are the one feeling this emotion, so take a look.  Is it connected to your sorrow, rejection, or pain.
Are you blaming the people or situations around you?  Most of the time we lash out to the people around us, they are just there.  Research how you’re feeling.  This is usually related to old stuff.
Get curious about what is going on with the other person.  They could be acting this way because of their old stuff.  Get interested in how that person is reacting to what is going on.
Get compassionate about the other person.  Develop understanding, with civility and empathy.  Get to know how this complex person is working.
Communicate your perspective by using statements that start with “I”.  Ask the other person to share their view and listen with sincerity.

LENS neurofeedback can help the person to be less reactive.  Come and try it out.
