Sometime in 2021 I was at kind of a low point and happened to play OMORI. It deals with many of the things I'd been struggling with at that time and taught me a lot about them. Naturally, I was obsessed with it for a year or so, and still think about it a lot.

Also, I've seen Outer Wilds mentioned in these kinds of threads multiple times now. I should probably just give it a try already...
