Reads like a slightly more verbose Hemmingway
I love the amount of stress you manage to develop and portray over the course of a scant hundred non-repeating (!) words. The use of elipses in this train-of-thought-type narrative is very effective, even to the point that I would have liked to have seen one more, after 'Almost finished now'
If you choose to treat this as a wip, I would suggest replacing 'another' with 'final', to further heighten the stress level, but be true to your muse.
I hope big rewards did follow for you. This is a truly challenging form, and you created an exceptional piece.
