You'll never know

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 oughtta 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 every 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.
