My past just slips away

I'm not who I wanted to be,
but you make that okay.
I lose more of my regrets,
with every passing day.
When I see you smile at me,
with every word you say,
You bring me up a little more,
and my past just slips away.
Before you loved me,
My world was always gray,
But you light me up inside,
With words, I can't explain.
I'd be lost without you,
I'd die if you went away,
But I trust your words,
And I know you'll always stay.
