The problem inherent is, as little bear said earlier, it is prose. His points are pretty much spot on for prose... the sentence structure is too simplistic. I appreciate that there is some use of poetic devices (simile, metaphor, etc.) but every instance it's another clichè. It's all too... teenage for its own good. It angsts as much poetry tends to do and it's boring.
From a purely structural standpoint, I have to wonder if you were shooting for prose or poetry (though either way it does read as prose) and I do at least appreciate the lack of unnecessary enter interjections, but... stanzas and other such nicities are appreciated and help the reader visualize rhythm.
That said, there really isn't rhyme or rhythm. Issue. Poetry really needs rhythm to make flow.
And lastly: there needs to be something more than "She is..." "I am..." it detracts from everything, makes it boring, and makes it cliche.
Keep writing and refine yourself.
Disagree? That's fine. I invite you to take a look at my poetry - not as me saying "ha ha I'm better than you" but so that you can respond to it. Tear it to shreds if you like. It's all good as long as you give me some feedback.
Here you go.
