"Empty Heart" lyrics

There's a hole in my heart that's shaped like you
And it's just big enough to let you through
My whole empty heart's just like a cup
Fill me up fill me up fill me up

Calm in my soul when you're with me
Peace in my heart that sets me free
You're the one that I call to fill me up
Fill me up fill me up fill me up

Now I know the reason why there was such a hole inside
'Cause I needed you in my life in my life in my life
