"Crazy" lyrics - JOHNNY CASH

I'm crazy, crazy for feeling so lonely
I'm crazy crazy for feeling so blue
I knew that you'd love me as long as you wanted
And then some day you'd leave me for somebody new

Worry, why do I let myself worry
Wondering what in the world did I do
I'm 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
I'm crazy for thinking
