I honestly never ever thought about it the way everyone else seems to. The first time I heard this song I felt it was about someone who had died and how difficult it is to become weighted down by the grief and sucked right back into the sadness of losing him/her. Waking up each day, painting on that smile and wanting so bad to break free from the chains. But the person continues to consume your thoughts and no matter how hard you try, you can't think of anything else. You just need to let go.
Maybe I just wanted it to be about this because for some reason this song explains my feelings towards someone who I lost almost 6 years ago.
