What do YOU think this song means?

This song is one of the most meaningful songs i've ever listened to. The message is fairly simple, but the way that he expresses himself throughout the song is so real, and so full of emotion that you can't help being drawn into the song. Maybe its just because i have been in exactly the same situation myself and i can empathise with the lyrics, but the hopelessness of his situation is depicted with the great contradictions. You give it all, but i want more. Nothing to win, nothing left to lose. The basic problem is that being with her is too hard to bear because he wants her so much, and being away from her is too much for the same reason. On a bed of nails she makes me wait. You give it all but i want more. He is showing his mixed feelings. He is angry that she is letting him stay in this situation, yet he knows that she is doing all she can. Hrmmm...i've gone on for a bit haven't i...it's just that this song is the story of my life, so i kinda could talk about it for a while...but i guess i'll just leave it here...
