I don't seem to have as much anger. I have had to work on it lots and the payoff has been understanding how anger worsens my illness.
Anger is such a strong negative emotion.
It will make you sick. I agree its better to let it out, otherwise it just eats at you, literaly. It depresses your immune system and God knows what else. It can be worked through however and often released without the need to pound pillows or kick the dog. I also agree that beneath anger is fear and shame.
