When I'm stressed at home, I listen to classical music or I cook, or play the piano, just to alleviate my tension. If I'm outside, I go running. If I'm at work, I go to the highest part of the building and close my eyes for a couple of seconds, then scream at the top of my lungs.
If I'm at the point where productivity does not ensue anything that would calm my emotional distress, I would sit on anything I could rest my buttocks, stare at a wall or anything that my eyes ganders, and pat my fingers then get some menthol cream and rub it my forehead, and wait until I fall asleep.
