One, there is one word to describe this feeling...
Endless.
For me, it endlessly repeats...
endlessly, my screams repeat.
Your right arm tastes so sweet!
It's maddening, so does your left!
I scream with a smile on my face...
It's happening again. It's so enjoyable...
I'm falling into madness, just as I wished...
And it's so enjoyable!
I'm shaking, .. I can't control myself anymore...
I'll kill you!
Controlled by sweet hallucinations,
I play a tune that blooms from my five fingers,
As I gouge them into your neck.
Will my thoughts not reach you?
Whose reflection is that in your eyes?
Do I even care if my heart returns?
Will carved wounds never heal?
Realize these feelings, why won't you realize them?!
My insanity is overflowing, how can I stop?
If I crush my feelings, what should I strive for?
Those screams coming from your strangled throat...
the melody becomes a vermilion rainbow.
This hue from slaughtering you,
what a sweet red color it releases!
I ascend this stage, as screams come from your shriveling throat,
This stage where I dance alone.
Has that wish collapsed? Have those thoughts been suppressed?
The true me is no more. I'll tear this life to pieces.
Such transient life, so beautiful and precious...
I'll scatter this life like flower petals.
You'll become mine forever, you can't be by my side forever...
So you may become a corpse at my feet.
I want to stay in this beautiful night...
This night, so red and so sweet!
And I want to be rid of you forever...
So I didn't really find much fault with this but I do think that you should probably work on finding a way to make it flow better. I don't know exactly how, because I don't have the poem right here in front of me, but I do think that's something you need to work on. I do think that some better punctuation would help, and if you didn't have such a big space between each line. Also if you write short stories, or even novels, this would be a great topic to write about 
Keep writing!
