Because I like to end on lighter notes, I'll start from the end and work my way back.
The final "I just can't" with the weird pattern of letters makes no sense. Of course it is easy to interpret it as the phrase being shattered like the glass, but since there is a pattern to it THAT doesn't even make sense I don't like the last line and how very telling it is anyway, but if you are going to have it, why destroy such strong words with that? When cummings used varied capitalization, it was for a very deliberate purpose. Think about why you're writing what you're writing.
The rest of this poem is very very telling. Try to leave more to interpretation and mystery. Use more of that brilliant imagery we learn about in class. Show don't tell, you know? Not to mention much of it is simply cliche.
The title is weak, but considering that this poem seems more like a draft than a completion, I'm sure you can develop that.
The first two lines are spectacular. The third automatically ruins it. When you say you're life shatters we ASSUME it shatters like the glass of a mirror would, so when you say "Like" and tell us what we already know, you make the beautiful image of you punching the mirror/your life fall flat. My advice is that you take this poem, start from those first two lines again, and create something fuller, subtler and rich with imagery and intricate emotion.

I already told you what I thought of this poem, but to say it again, I loved it =D Keep up the asume work! ~Rowan~

aw, very pwoerful. wow. i know this all too well. good writing!

I'll admit I'm a little tired of sad, depressing, bloody poetry. But this one actually made it to my "good side" almost unscathed. I really like the image of the mirror being not only a reflection of the person, but actually an extension of that person's soul and body--when the mirror shatters, you imply, it's truly the person shattering as well.

Your two-word lines annoyed me ("I can't / I just can't/ ...etc.). These are very short and very pointless. A few of them would've been acceptable, but there are too many. I'm guessing you were trying to make it sound kind of stuttering and emotional, but you end up seeming a little rambling and un-edited.

But, like I said above, this poem is actually very good. The mirror image basically saves it from any structural problems. Nice job.

It even hurt.

I really like this. I can relate... Nicely done...

I like it a lot.

*snif,snif* I feel like that sometimes... i think we all do..GOOD WORK

nice job. keep up the good work
