I find it moderately surprising that, looking back at my Twitter/Mastodon output, it hasn't gotten all that much grumpier over the past year.
I'd rate the last year as the worst year of my life by a decent margin, significantly worse than the childhood years, where I was regularly lightheaded from hunger, was malnourished enough that I broke my collarbone from rolling off the couch, was regularly beaten, etc.
Ex ante, I would've expected much grumpier output from me.
