I think the optimism conveyed by the music is supposed to be ironic or at least counter the lyrics. I think the lyrics are supposed to be empowering. Don't stick around and wait for someone or something if they're not reciprocating the feelings. Having hope in that situation is only going to delay what should be your ultimate acceptance and ability to move on and be happy with yourself. If you can't handle yourself in the given situation and move on, then you've gotta run and you've gotta run from that hope that's holding you by a string.
