Without You - Three Days Grace.

What if I walk without you
What if I ran without you
What if I stand without you
I could not go on

What if I leave without you
What if I love without you
What if I die without you
I could not go on

You left my side tonight
And I just don't feel right
But I can't let you outside
Without you I'll know what I'm nothing at all

What if I lie without you
What if I rise without you
What if I dream without you
I could not go on
