Welcome to Gaia! ::

this one seem to be made up of cliches, and some spelling needs to be corrected ^^
the line praying for darkness 'divine' is quite good. perhaps a rewrite?
good luck ^^

The Golden Rule of writing: Show, Don't Tell. A clue on how to do this: BE SPECIFIC ON ALL DETAILS. This isn't all. But it's a starting point.

falling faster than the atmosphere can catch me
pumelling to the death of my soul It's plummeting. "Pummelling to" doesn't make sense, "pumelling to" even less so. (pummel: to punch, plummet: to fall.) Also a cliche line. You don't want to tell us your soul's dying. You want us to see it.
meeing my fate with utmost dignity At this point, the reader starts to think- "Really?" (Show us.)
hoping to finally be whole bland. very cliche as well- I'd cut the line entirely.

losing myself to the screaming silence Trite paradox. Yes, there are such things. Paradoxes are unusual juxtapositions that make the reader pause and think, and then say "It was very appropriate and witty in context." This one, meh, you see it so often you forget it's a paradox. Snip it.
praying for darkness devine Divine. Better paradox.
finding my voice in the moment of last cahnce Chance (sp). This is where I thought, "this sucks." The narrator's point of view does a 180 with no explanation for how it happened; epiphanies need reasons for occuring in poems as well as they do in stories. You listed a conflict and a happy ending without a climax. Think of Cinderella where the Godmother never happened, the lost shoe never happened- she just ended up married to a prince one day. Doesn't hold water.
finding myself to be fine Again. I won't be reiterative- look above.

trying to lose in the war of the heart So there's a single hypothetical heart that's warring internally now? Look, you can't do this to your audience. You turned out "fine" in the stanza above and here you're a maniacal, depressed IWANNASLITMYWRISTS let-me-lose-everything maniac again. The end of the poem, the denouement if you will- that's where resolution occurs. And then you stop with the new angst. OK?
losing to life's betray (I hate this line) (So do I. It's gramatically incorrect. You can't lose to a verb. Losing to life's betrayal makes better sense.)
trying to lose my life's meaningless part I think this line's worse than the line above. Of course, you have the option of cutting lines. Also, you have never specified what of life you find meaningless and why, so the reader will have no sympathy.
lising why not to stay ...WHAT? (lising is not a word.)

falling faster than the atmosphere can catch me
pumelling to the death of my soul
meeting my fate with utmost dignity
hoping to finally be whole Look above.

Repetition might work in this poem- but this needs a complete re-write before it can be called that.

General warning: "I was thirteen" is no excuse for posting what you would consider crap. The author has an obligation to fine tune until their work is the best it can be, before handing it to potential editors. You show us disrespect in expecting us to deal with what isn't your best work. Further, pretty words strung together does not make a poem. Nor does a string of pretty images.

There is no excuse not to run a poem through a word processing program with a spellchecking program intact, preferrably coupled with a grammar checking one. I've heard the arguments, spare me. I know that artistic license allows you to break those rules. But that artistic license is not an excuse to make mistakes- artistic license is a license to consciously break those everyday rules to improve the poem.

...I really hate hearing "I was only thirteen" excuses. Go edit already.
