Hmm. When I wanna relax, I usually just play a video game. I get really into the game and end up losing track of the world around me, so for me, that's relaxing. It's especially helpful if I'm feeling negative. I can vent my frustrations on my victims.
I usually go away to be by myself and listen to music and write.
Or, if I have a game system near me, I'll play a game instead of write.
Sometimes, I'll just lay down and listen to music. Music helps a lot.
If I'm really angry or frustrated about something, I'll end up throwing something really hard at the wall. >>
It...it helps...and then I'll lay down and listen to music or something afterwards.
