This is what Missy Higgins supposedly said about this song:
"That song is about depression. It was written for a friend going through something that I had experienced before. I came out the other the side, but I know how tempting it can be to give it all up and stop trying. When it comes down to it, its really important to have people to prop you up. I was trying to do that for her."
I just have a big "thanks" for those of you who have propped me up until I got to the other side.
