I think this song is about how in life we get so caught up in materialistic things that we forget about the only thing that actually important in life God. The phrase "i think i'm moving but i go nowhere" means that no matter how you think youre getting to the top your actually not going anywhere because this wont matter if and when you get to heaven. The phrase "but i've become what i cant be" meaning that he's not happy with how and why he's become who he really is.

Dude I feel for nick and all but its not like he has cancer or anything its just diabetes. We can get through it. I ve come to know that diabetes is not the end of the world. Were all normal and its just a blood defection! I love you nick and omnipods rock and whoeva thinks ur g* for wearing one is absolutely stupid but I love th fact that this song isn't just about diabetes its about anyone with a disability or an obstacle in their way of chasing their dreams and the jonas brothers didn't make it to the top cause of their hotness or materialistic things its cause they have there priorities straight and they know that the only way to live is to put god first and dream big we should all follow the awesome example that they set for us I truly believe that the message they send is a me ssage that every1 should learn.
