I tend to use music to help me deal with the world, but when I've had a rough day, I just need to get away from people. It would be better if I didn't have the internet, because I just stuff around, surfing randomly. That never helps anything, and only makes me more frustrated. I know I would feel better if I rode my mountain bike, or did anything to get out of the house, but if no-one makes me leave it, I'll be in my room: It has my computer, my HiFi, and my guitar.
If I think my housemates aren't home, then I will stomp around the house, making a racket, punching door frames, and other hard points that won't take damage, bellowing my frustrations. It usually makes me feel a little better, particularly if I know what is frustrating me.
