As it mentions two people throughout the song, I believe its about someone in a relationship that's falling apart. The writer wants to deny it with all his might, believing if he does, he can salvage it, but he knows inwardly that it can't be saved. Its not clear about the second person's oppinion in the song, but the line "the whole world can just go to hell" makes it clear to me that the writer doesn't care what he/she thinks. All he knows is his world is falling apart, and he wants to deny it.
