Have you ever driven down the freeway in your car screaming at the top of your lungs? I highly recommend it. It's a great form of catharsis.
I have a cloth doll that I throw at the wall. If I am by myself, I also scream and curse as IM throwing it. However, if I am at work and have to keep my composure I just take a quick walk to the bathroom and take a few deep breaths while IM running some water etc.....
usually just cry when I get mad...I hate it.
I scream... internally... and write a tweet :D
Right the FVCK now !!! ughh
I grab some music and try to find something that goes with why i am feeling then I throw a couple of things
Scream---or plug in the guitar and turn up the amp
