It might not work for you cause you know it need not but this works for me.
I lock myself in the bathroom and scream for a bit and then wash my face with cold water. Repeat until I calm down.
Walk around in silence and all alone and if possible take deep breaths out in the open. No one should be near me.
Put headphones on and listen to aggressive metal music. It helps my friends, it helps. Singing out the lyrics and punching the air in beat with the music does go very well too.
A little booze after I have calmed down a bit also helps. And some good food. But it has to be a while after I have blown off steam, atleast 30 minutes or so. And I won’t drink anything hot – that would be like putting more heat in me!
