The most
Ago-
Nizing
Feel-
Ing of all.

Is seeing
The
Pain
Not that
You've caused
Yourself
Throughout
Your life,
But rewinding time
And seeing
The disgust
Sadness
Sorrow,
Hurt
And
Pain you've caused to those that you love the most.
As you want to go back
In time and fix what's been destroyed or lost.
Then all's gone, all's already ruined, forgot.
