This sort of reminds of a recent conversation I had with someone about heaven and hell and that tacky comment that people make about the nonexistence of hell and heaven and that we are actually living in hell.
It's a very riveting write. Your view appears to be slightly not to say very nihilistic which appeals to me a lot!
It seems as if you are trying you portray the moment before one dies ... when nothing makes sense ... it sorts of made me see an old man with a thousand regrets and looking back at his life with remorse ....or perhaps you were just gnashing your teeth while recalling something bad someone did to you which doesn't seem to be a completely unrelated feeling, to boot.
As to your style, I must say I like the intensity your manage to convey.... it seems as though one - or perhaps some - can only portray such emotions when dire straits are faced.... which sounds a little dejecting ... I also liked your imagery as you might have noticed.
The only critique I have has to do with the first and second stanza. You may want to re-think or re-write some of those lines considering that some of your line breaks sound a little off and hinder the flow ever so slightly.
