Okay, judging by the capitalized He's and His', the song at least ends by talking about God helping her, not a normal person like her boyfriend or, in the video, her dad. I don't think either of the girls was supposed to be Renee, especially since she made a cameo in the video. Their situations were supposed to be similar (depressed adolescent girls that resort to cutting to deal with their pain), but I think they were both featured to show that depression can happend to anyone. While the range was only two girls, both the same age (making a rather limited range for "anyone"), these characters were designed to be on totally opposite ends of the social and possibly economic foodchains. It has a lot of truth to it. It really can affect anyone, even people that you may not expect, and there is always someone there that cares for you. You can make up your mind that there isn't but you're wrong (like the first girl and her father; she most likely believed he didn't care about her at all, but in the end you can tell that he really does love her). Maybe you haven't met the person or people that will care about you from the moment you meet on. Yet. You will. If you didn't know, though, the song was written with Renee Yohe as a muse. Renee is the person that ended up beginning a movement titled "To Write Love on Her Arms" which was created to help the suicidal and those that cut themselves.
