Darling, I'm so blue without you 
I think about you the live-long day
When you ask me if I'm lonely 
Then I only have this to say

You'll never know just how much I  miss  you
You'll never know just how much I  care
And if I tried, I still couldn't hide my love  for  you
You ought to know, for haven't I told  you   so
A million or more times?

You went away and my heart went with you
I speak your name in my ev'ry prayer
If there is some other way to prove that I love you
I swear I don't know how
You'll never know if you don't  know  now

You'll never know just how much I  miss  you
You'll never know just how  much  I   care
You said good-bye, no stars in the sky refuse to shine
Take it from me, it's no fun to be    alone
With moonlight and memories, 

You went away and my heart went with you
I speak your name in my ev'ry prayer
If there is some other way to prove that I love you
I swear I don't know how
You'll never know if you don't  know  now.
