nerve induction in poetry

Like Paul and the pain box,
I’m learning not to flinch,
learning the burn is an illusion
and to not move an inch.

The feeling that there’s a better you,
sleeping inside,
but you don’t know how to wake him.
We need a word for this.

Like Paul and the pain box,
I’m trying to prove I’m a man
by taking attacks while smiling
holding out for as long as I can.
