Don't Look Back

You turn around,
You walk away,
And don't you dare look back.
If you look back,
If you turn 'round,
You'll surely see me fall.
I will collapse,
I will lose it,
And you'll see me shatter.
Don't you look back,
You turn and run,
While I fall to my knees.
So in silence,
I let you go,
Even though it's killing me.
