Without 歌词

I can't understand, what's bring you down, Won't you tell me? I was alright, up 'til tonight, Now I've gone. You can't stop thinking about her, So long, you've been without her. Come back to bed, and rest your head but you won't. I can't even say, why they went away, I don't know. You can't stop thinking about her, So long, you've been without her. (x2)
