SOLVED. YA Sci-Fi Dystopian (hunger agents era ?) book 2010-2013 ish. Spoilers. [s]

Okay so the I read this book back in middle school/ high school when sci fi was the trend but I don’t remember if this book was released around that time. I believe I got it from my middle school but honestly the details are a little fuzzy and I only really remember the ending clearly.
The plot that I can remember with SPOILERS FOR THE END are :

A book where a seniors in high school are stuck in their hometown with no way of escaping/ Maybe their in a time loop and one the main character notices? Something along those lines but the 1st part seems closer to what I remember.

Their a meteor show that’s happening sometimes when the summer is ending/ graduation. (Something along those lines) And some of the towns people are saying it’s gonna end the world.

ENDING SPOILERS :
In the end the whole class finds out it's all a simulation and a meteor has hit their town and killed everyone. Their parents choose to save their kids and put them in these like cryogenic pods to sleep/ just upload their minds to this device.

It’s something along those lines I’ve recently been trying to reread all my old book from when I was a kid and this would greatly help! Thank you!

Nemesis by Brendan Reichs? It was first published in 2017 so possibly too late to be your book, but I believe the twist is very similar.
