Sorry to hear that. Those break ups really sucks.

The few times i've tried it, music has been mu guide and healing. I always managed to find the most depressing music and play it over and over again, until i grew tired of being sad and sorry for my self.

Go see your friends, tell them how you feel. Some of them probably will tell you that they're not that interested, and others listens, gives you that sense of friendship as it really should be. In the end your everyday life wont hurt like now, but you'll remember what went wrong (if anything did) this time, and hopefully do anything to prevent it from happening again.

But as others have said, don't do something stupid to your self, nothing good will come from that.
