To me, its about feeling so great, on top of the world..Then something knocks you off and you fall into depression. You feel like you've lost everything. And Andy actually said its kinda when your sad and angry and all these negative feelings and people are saying to you "come on dude/girl get up and do this!" and sometimes you just don't feel like it, the song is really saying its okay to feel like that, its okay to have dark moments in our lives, but we all fall down sometimes and we pick ourselves up.
