It's always seemed to me that this song is a plea to stop trying to fix people. It progresses from "Thanks, but I'm broken" to "I'm bound to be broken" to "I know I'm not broken". I think that even though there are clearly separate characters, they're not really separate. Multiple characters makes the concept universal. And even though your life could be hard and it seems like a total mess from the outside, that doesn't mean you need to save them. (I use save very specifically here. Meaning: save as in "make a project of turning them into an example of your morals" not assist them with what they ask for)
