Cradling Destruction

[carahmellow]

I've fallen in love
with a bomb, disguised 
by glittering diamonds.
Every time I misstep
it ominously rumbles,
the light slowly fading away. ("slowly fading away" is too wordy. I think finding an impactful word it its place would be more effective (dissipating, retreating)
In blindness, I failed to recognize it (the blindness is a bit odd considering you were aware of the glittering diamonds... and the "light fading".. this would not be seen if blind)
now in idiocy, I keep it close. (remove now)
I need the diamonds to live, (why do you need diamonds to live? maybe you could change the diamonds metaphor to something else, and this could clear up some of the other issues above)
but the bomb will surely end me.
My health lays abandoned (lies would be the proper word choice)
as I cradle this explosive,
desperately trying out of love (Desperately trying, adverb check... see below) - I dont feel like this line is as impactful as it could be. "out of love" feels clunky)
to save this bad omen.

Overall, I like this idea, I just think some of the metaphors don't work quite as strongly as they could together. Always remember... adverbs can sometimes be combined with the word before or after to make it stronger, more impactful, and less clunky. Not always though... 
ex: gently die: Wither or Slowly fade: Dissipate...

Also, watch your "extra words"... usually you will find them at the beginning of lines. This is something I have to be aware of with my own work, as I often use them without realizing it. when I recite the poem without them.. they sound so much more intentional and clean. I have gotten a lot better but its still something I have to be aware of.

keep writing, I love reading your stuff.
