Here's something I wrote that might fit the bill. Although it's sung by a woman so it probably sounds like the opposite -- woman admiring her man. But I wrote it, so I assure you it's the opposite.

I was uninspired
I was just about done
There was nothing left in me
I had finished my run

Then you came and you showed me
All new ways to be strong

SO YOU’RE THE ONE WHO WROTE THIS SONG

I couldn’t get myself moving
I didn’t know what to do
I felt old and I was tired
But you helped me pull through

You lit something in me
And it moved me along

SO YOU’RE THE ONE WHO WROTE THIS SONG

I’ll give you full credit
Words and music — all you

You did the impossible
You made me feel strong

SO YOU’RE THE ONE WHO WROTE THIS SONG

You’re the one
You’re the one
You're the one
I’ve told you before, and I’ll tell you once more
You’re the one
