Sleeping Alone Again

Without you in it,
My bed is the worst place to be.
I can't sleep tonight,
I need you next to me.
Your pillow cannot fill your space,
And my memories sadly take the place
Of your sleeping form.

Why is it so hard to sleep alone?
I thought I was full grown,
But any more, I can't do this on my own.
This is something I should have known.
Even though you will be back with time,
I can no longer call this place mine,
Because it was ours and you haven't left my mind.
When the night comes that you'll be forever gone,
Know that I'm coming, and I won't be long.
I'll just have to tell a few old friends goodbye,
And since they're memories, they won't cry.
