Counted Is Bygone

I skin myself
This aged tissue
From the inside
This tremble is unbearable
I wrap it up
My think tank
An useless gift from me to me
I sent it out
But I ran afterwards
Caught up and unpacked
Staggering by debility
Copy of the blood machine top left
Pump you bastard pump
I know every beat
I count them all
I know every beat
Counted is bygone
