"Crazy, I'm crazy for feeling so lonely /I'm crazy, crazy for feeling so blue
I knew you'd love me as long as you wanted / And then someday you'd leave me for somebody new / Worry, why do I let myself worry? / Wond'ring what in the world did I do? / Crazy for thinking that my love could hold you / I'm crazy for trying and crazy for crying / And I'm crazy for loving you" (Willie Nelson )
