Thats not a very healthy way to let it out. I know we all do it sometimes but what you really need to do is talk to someone. If it helps even go vent on this sight so you don't have to tell people you know. Music does help, but not when you use it to just totally ignore your problems. If you continue doing that, it is eventually all going to get to you and one day your going to snap. Keep from snapping and find some other ways to let out your frustration. Work out, write a poem, vent it out, talk to a friend, talk to a counselor, anything to get it out of your system.
