Words in memory

My words fell uselessly at your feet,
And now you are trying to sleep,
But they have risen to fly
All around your head at night,
They won't give you peace, my friend,
Those words were precious,
Each one of them
And every word has a price
That you will have to pay,
Ever more and maybe throughout,
And you should know this,
Those words you thought useless
Were never useless at all,
They're ghosts from your past
That won't leave you alone
Even when your scars heal,
They're enough to cut it open
With memories enough to destroy you
To even finally end you.
