I would fully agree that this is about his girlfriend committing suicide and being condemned to hell. My guess to the one of eleven is that she came from a family of eleven kids. ("One of Eleven") I also conclude that she was sexually abused as a child ("Who had been rendered unwhole
As a little child. ") and eventually taken from her family and the bounced around in the hell they call foster care. ("She was taken, And then forsaken")
