I see a lack of propper punctuation and a certain grammatical typo or two. I'll give the few suggestions I can, perhaps guide you into reviving this poem, probably into a more symbolistic-ish view.
" This floor is cold, like the blood my body pumps, with my fingers gouging in my eyes... "
The need for the ( , ) there is quite obvious, you cry out the lack of life within you. The triple dot at the end would add a tinge of intensification of the moment.
"And the suicidal thought, brushing this freeing feeling in my mind... " This time, the ( , ) is present to make the comment itself have more appeal. The extra dots have the same role once more.
"I wonder, how is it possible to be in love, when I only know the hate? " Corrections added:
( , ) - the role of it is very much like before ;
( in ) - this was added, as you can't "be love", you can only "be in love" ;
( ? ) - Author's question, designed to intensify, put an ironic question that won't recieve an awnser, or otherwise.
"If I scream, I wouldn't be heard, as if the world had blocked me out... Rejected me. Abandoned me...
"I now see.. ", said the blind."
Extra ( , )'s, amongst the replacement of "like" with "as if", as it's more appropriate; Had instead of Has; ( ... )'s added to intensify the exhasperation, the depression; "I now see.." now has the purpose of monologue, as in, the author speaking towards himself, as if someone would be picking up the message, or taking note of it; some times, a higher power, such as a divinity could partake in this, but most of the times it could simply be the readers.
Do this, and in my opinion, the poem will look much better.
