Song Help? I Don't Wanna Be Alone

I need help identifying a song I heard on the radio.

The only line I could catch that was repeated was "I Don't Wanna Be Alone, I Don't Wanna Be Alone" and it sounded like Good Charlotte although it probably isn't.

Any help would be greatly appreciated.

It is, you are right

Good Charlotte - Dance Floor Anthem
