This is rather..breathtaking. First of all, i adore the structure. it's just...it's different. there were a couple rhymes that sounded a bit forced, but other than that it was lovely. I loved the last...stanza/paragraph. it was just gorgeous, really. and the last line, vocabulary!!!! lol. wonderful job, m'dear.
"And yet I feel the doubt creeping upon me, exploding and covering the surface, seeping into the crevices, falling drop by drop into my bloodstream, mingling with my blood and playing with my heart and mind.. I see the mirror, I hear the envy, but all I feel is desolation. There is a boundless universe of emotion, and I feel so much of them and then none of them at all. I know nothing, and it scares me. But I know so much more than this... I know that, but in comparison, I still know nothing."
Though you wrote this part paragraph style, it was my favorite part, I think it was because you let go and didn't try to force rhymes, it just felt like you were spilling your inner thoughts. Keep practicing and working on it, you definetely have potential.
