To me, the song means that he can't take the pressure of life as it was, and that he's tired of being scared. He also seems to mean that we, as humans, tend to rush through life, not opening our eyes to what is around us. We only see life from the beginning, birth, and the end, death, we don't focus on the now. Just the past and future. And because of this it is meaningless and we are all "less than nothing".
