Dr. Frank - Sad, Sad Shadow lyrics

I don't know why but somehow there came to be Across my heart and on everything I see Upon the earth and deep inside of me A sad, sad shadow It's not the way it's supposed to be I guess But I can't imagine otherwise I must confess Tell me why I'm so full of emptiness And sad, sad shadow It's a secret I know I'll never find For what purpose am I so designed And what has cast across my heart and mind This sad, sad shadow
