Why I can't sleep at night sometimes

At night,

Theres a million and one things that keep my mind awake.
I'd count with my fingers but your holding my hand
enough to keep me warm this cold night I shiver,
lying on the floor.
I can tell your asleep by the pace of your breath
and how it changes from one moment to the next---
So I wonder,
if my world ever falls apart,
will my words ever mean anything
to those with restless hearts.

Enjoy.
