You obviously have something that you need to let out... I completely understand where you are coming from.
I am going to offer some suggestions here... and hope that they do not offend you. I personally view editing as something almost pleasurable... like perfecting a pedicure... it's a sort of fun game.
First of all, since poetry tends to be so short, it is extremely important that you choose each word as carefully as possible... to get the impact that you are looking for. Avoid repetition unless it unavoidable, in your opinon. And by all means, avoid cliche. Nothing will get you ripped apart faster...
But most importantly, keep writing and keep reading. Nothing will make you grow more as a writer than by reading others that you admire... and by writing yourself. I hope the edit below helps illustrate my points somewhat... I wouldn't have taken the time if I don't think that you have a large amount of potential. (Not that I think its better, by any means... just more to the point...)
Oh, and also, keep in mind that you have five senses to work with... as a writer you get to illustrate everything...
Elastic band wound
until i snap.
the voices in my head
have been released.
this technicolour nightmare.
forms blossoms...
my nightmare
is in bloom.
Your whispers
from the back of my mind
are cunning and callous.
Sneaking, slipping
through my thoughts,
carrying panic
that i don't want.
I snap
and
f

praying that
someone will
catch me,
but shattered
there is no one.
No security now
but there never was.
I watch the knife
on the table
as it spins.
Light reflected from
its point.
Its point now
flirting with my skin.
(Notice that the ending leaves your reader hanging slightly, wondering if you will actually go through with it???
