You're the medicine

I'm hurt 'cause you're not here.
You're the only one that can heal my pain.
You're the medicine for my pain.
But now I'm hurt 'cause you're not here.

The pain will stop when I see you again.
Without you, my life is void and empty.
You're the medicine for my wounded heart.
You're the only one that can save me.

But for now my medicine has run out
'cause you're...
not here.
