Writing like this is hard to give critique on. Any input on the message would be detracting from what it is, which is just your internal monologue typed out quite poetically.

So I guess the only thing which we can critique is the structure and literary style - in my opinion (which hasn't been educated on this type of thing at all) it gets the reader thinking which is obviously what you were going for. It's very satisfying to read something we all think about when it's written in a way it would be quite hard for us to articulate. So well done for getting us thinking!

In terms of the message, well, I'm a physicist and this existential crisis you've written about is exactly what drew me to study Physics, so it's always nice to hear someone else is thinking the same things.

Keep on writing, I look forward to seeing whatever you come up with next :)
