"Antagonising shouts, piercing screams,
Ripping through the core of me.
Nothing is ever as it seems.
Never too hard to wake up and see."

^^I found the flow to be slightly of in the third line here, maybe try fixing that up a little?

"The blackest shadows shriek my name,
My back burns but my face won't betray
The amount of torture in this game.
Surrender is imminent, but not today."

^^I don't think you need "the" in the first line. I adore the last line here, I find it to be mixed with strength yet also weakness, which makes for a powerful affect.

"This twisted nightmare seems too cruel,
But fades in significance, compared to you.
Conquer insanity and I shall rule:
The voices in my head must be true."

^^Favourite stanza so far. The depth and emotion within these lines is incredible.

"Souls snatch snippets of my pride,
Disturbed immortals begin to cry.
At least I know I miserably tried,
Hands down, surrender, let me die. "

^^Okay, I changed my mind. This is my favourite stanza. The power in this stanza is unbeliavable, and I find this verse to hold more impact than the rest of the poem put together.
I love the last line here, I found it to be very hard hitting, and I had to read it quite a few times, and each time I loved it more and more.

Beautiful.
