HELP!?!? I'm trying to figure out a song title and artist.?

All I can remember about the song is that it starts off with a girl going to a club and the bouncer lets her in even though shes underage. Then she ends up doing lots of shots and cocaine because guys keep buying her drinks and what not. Then I remember something about how the guy didn't want to call the police as she pes out because he doesn't want her to get in trouble or something. But then he ends up calling the police and they arrive but she ends up dying. I don't know, that is basically what I remember but I hope someone will know what I'm talking about. Thanks.
