Time out
I've been taking time away from Mastodon, and to a lesser extent from social media in general. The number of people I interact with daily has gone down... but when I do talk to people, it's more in-depth, and less frustrating. And my mental health, I think, is improving as a result.
I don't think I was doomscrolling, but I was definitely a little attached to the idea of never missing a post, and accepting that I'm not going to see everything that happens is definitely going to help me in other ways if I let it settle in.
So I think I'm going to keep limiting my social media time - not formally or mechanically, like with a browser plugin, just... taking it out of my line of sight, so to speak, so that I only check when I remember to, rather than having it right there all the time.
