Okay...do any of you know what I'm talking about?

I'm wondering if anyone can tell me who sings this and what the song is called. I saw this music video a couple of years ago. I'ts about this girl who doesn't get along with her parents well. She meets a guy at a party or something. They are leaving because the cops show up. They get in the car and they get in a car accident. He dies and she lives. The end of the video shows her like sitting in the livingroom doing her homework...Does anyone know what I'm talking about. It's been bothering me for forever. If anyone can answer this it would be very much appreciated. Oh and the girl in the video kinda looked like Christy Carlson Romano. Thanks much...
