I've decided to try and disengage from Twitter by getting into mobile gacha games -- you know those games where you randomly collect stuff to play? (I chose Granblue Fantasy which is a JRPG with random characters/loot, but I've also played Puzzle and Dragons which is a match 3 with random loot).
While these games have, at best, a predatory financing model, I have noticed a significant uptick in my own mental health by replacing the casual Twitter check with the casual loot farm. I sleep better, I'm less anxious, I'm less impatient. Especially because a lot of the time I was looking at Twitter right before bed and seeing a constant stream of terrible news (and people being wrong on the internet, which must not stand.)
So, I dunno, I can't say I'd recommend getting into a grindy, random slot machine, but I can say it has been a salve for me right now.
