Yes it can feel big and powerful. A long time ago I had come to a point when I allowed myself to be angry, I somehow gave myself permission. I had done nothing wrong, but someone had blown up on me. And I began to get mad back. It took about three hours of driving before I realized that I had a million little red flags sticking up, waving,and saying I'M PISSED!!!!!!
As soon as I allowed myself to be angry, all the little and big points of anger that I had never felt, wanted up and out also.
Overrwhelming and powerful......anger is good when it is the correct anger. Good Luck .
