Music is my main form of stress release, that and crying. Seriously, if it wasn't for my extensive collection of music I would be dead right now... (well maybe not literally.) Plus I'm the kind of person that gets upset about the tiniest things so I often find myself coming home from school and just having a nice long cry. I do hate that about myself as well though, how much I cry, it's really quite pathetic.
Seriously though, listening to music is a great stress release. And so many different kinds as well...metal, alternative, easy listening, happy music and all have their place for all different moods. Music is the most wonderful thing in the world.
