You are describing my W. Thank you for sharing this. Do you apologise for this rage or do you feel justified. Do you always recognise it? What makes you recognise it. You clearly feel you have something to work on with this. What made you recognise this and are you really going to do the work. As it is tempting to say 'oh I'll sort it out' and not fully commit.
I once punched a wall and broke my hand! I had locked myself out of my room at university. I didn't do that again! As I have had to deal with my W's rages I have learned to control anger in me very well. I struggle with sadness and attachment at times but I am improving and will get to the points not that I feel completely in corntrol at all times. So I know we can change. It is tricky but I am sure you will get there.
