All by myself

I'm all by myself
Don't need anyone at all
Left on the shelf
That's the life I've formed
Is this all there is?
Is this all there is to come?
My children grown
Flown the nest: its best
But Lord I am unsettled
I had hoped to find someone
To spend the rest of this
Mortal life with...this time
Here upon this earth...
Do not want to do it alone
But how does one survive it?
How to simply get on and live
Without companionship
Without someone to hold my hand
