If everything ends, please don't leave me

It's something you always think about.
Can he really be gone?
Can I just be dreaming?
What a nightmare.
Why can't I wake up?
Have you ever felt like a piece of you is gone forever?
How can I continue to go on?
When you cry, my eyes they collapse.
I tell myself he's not really gone.
But it's hard to hug a ghost.
What a nightmare.
Why can't I wake up?
Don't leave me.
Don't leave me.
I'll never forget the times we shared.
The love we'll always have.
Please don't ever forget me.
You know.
You'll always be a piece of me.
