i too have a great deal of almost constant seething anger. i used to do competitive sports but found that ultimately they made me even angrier. i discovered peace wonder a sense of personal power the release of anger and adventure in hiking and walking. suggestion: get an ipod or similar device if you can with some of your favorite music on it. find a nice park and look for good hiking trails. wear rugged clothes and good shoes. don't push too hard just hard enough to release tensions burn up the excess stress hormones such as adrenaline and cortisol and bring forth your body's natural endorphins and serotonin which will make you feel good and appreciate the beauty around you. after you hike stretch to cool down to prevent muscle cramps and be sure to rest well; allow more than enough time to sleep and clear your mind of worries as you rest. i live in a noisy place without as much privacy as i'd like and i use my ipod when i rest too with soft soothing music that helps me fall asleep. some people use a fan or other "white noise". when you are actively angry you cannot digest food but once you've calmed down eat food that will replenish the resources you've burned up because anger uses up a lot of the body's natural fuel. be sure to stay hydrated throughout. it may take some time but gradually this just might help. good luck.
if i have alot of anger stress and emotional baggage what is the best sport i could exercise or learn to help me vent?
