I noticed that I have been finding myself reading articles and discussions on stressful subjects I can't do anything about (ranging from "things I should donate to if I had net positive income" to "hanging out with friends"), and the resulting feelings are clearly not doing anything good for my health. So I'm filtering: anything sufficiently stressful that shows up in my feeds gets removed/blocked/"I don't want to see this"'d. Still working on convincing myself not to read the comments on SSC's "Things I will regret writing" articles (I should just avoid those articles entirely, eventually). One can't very well unlearn helplessness when constantly indulging in reminders.
