This comes across as a fairly garden-variety creepypasta in setup and execution. That's not a ding on it for me personally, as I still enjoy creepypasta and its descendants, but the establishment of that trope early on sets a tone that isn't really doing this any favors. It tells me exactly where this is going to go and what will happen, and it pretty much plays out that way to the letter.
Adding to that worn-out feel is the presence of the standard-issue Irreverent Agent What Doesn't Play By The Rules. I feel like I've seen this perspective in Foundation narratives so many times that I wonder who's left to do the real work like filing reports and forms and what have you, since everyone else is too busy being a smartass or whatever. The way the guy writes is also very reminiscent of a late teens/early twenties guy on the Internet. I'm not saying that such a person would never be in that situation, but again, one gets tired of reading the same viewpoint, even if it's not surprising to see most of our membership write in their own voice all the time.
All of that could be forgiven if this packed enough of a punch to the reader to make them forget all that stuff, but I found that the place this ended up was unearned. I would imagine that a person trapped in an inescapable, neverending anomalous plane of existence would eventually get pretty unhinged, and may indeed choose the course of action of your narrator. But reading it, I get this almost blasé "well, guess it's time to eat my gun" feel from it. Maybe that's a product of not being invested in the character, and maybe it's partly because that's 100% where I expected this to go, but I feel like you could have done a little more to set that up on an emotional level. Ultimately, as a story, it doesn't do a whole lot for me.
