I love the idea, the perspective from the point of view of the zombie. Decent twist that he’s not a classical brain eating zombie.
The paragraph that start, “I trudged down…” is a huge run-on. You may actually have the punctuation right for it to be a compound sentence grammatically, but it’s still way too long. You can get the same effect with a succession of simpler sentences.
You also slip into past tense at the end of the second to last paragraph.
So, technically, so cleaning up to do, but a great idea and feel to it.
