Kristoff Lullaby (From "Frozen: The Broadway Musical")

What is this hollow kind of helplessness I'm feeling?
This type of terror is new
And, the fact that I can hardly breathe is now revealing
How much I've changed 'cause of you
You light the world for me
You live life fearlessly
Braver than the bravest of us do
You trust, you hope, you dare
You choose to feel and care
I thought that I was strong 'til I bumped into you
What do I know about love?
What do I know about love?
Everything I thought I did
You've gone and changed it, kid
You're what I know about love
