Getting news via RSS feeds helps. I also cut out what is obvious just bad and getting worse for instance Gaza and Westbank via EI news. I know its getting worse but I cannot take hearing about every death.
Also, I think realizing most doesn't affect you individually is helpful.
Because you don’t keep doomscrolling. You subscribe to your most important sources and ignore all of the noise of short form posts. If something is truly important enough that I really must read it today, then at least one of them will have written about it.
The filtering out of what you don’t care about has already been done. That means I have a reading list where everything is a 100% must read for me and I keep it manageable
I find it better because I can choose exactly which feeds, websites, and creators I see all in one feed. Therefore there is little chance of seeing something I have deemed undesirable. I also like it because I can follow people I like on youtube without having to sign in! :) Prior to making my own lemmy instance I would follow specific coms and reddit subs too. Now I don't do that because I just ban rude people or coms.
Also, I rarely go to new sites. Accessing them via RSS allows me to only read content without ads or trash articles not related to the feed I want.
Finally, it brings all content together. Humans are lazy. It's hard to go to a ton of different sites to form an opinion. It's much easier to put it all in one place! :)
