Crazy lyrics

Crazy, 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
[ Lyrics from: http://www.lyricsmode.com/lyrics/s/shirley_bassey/crazy.html ]
Worry, why do I let myself worry?
Wondering what in the world did I do?
Crazy for thinking that my love could hold you
I'm crazy for trying, crazy for crying
And I'm crazy for loving you

Worry, why do I let myself worry?
Wondering what in the world did I do?
Crazy for thinking that my love could hold you
I'm crazy for trying, crazy for crying
And I'm crazy for loving you, crazy
