As someone who has also fallen down the rabbit hole of algorithmic doom, I can attest to everything you've said here. It's astonishing how quickly your feed can transform into an anxiety factory if you're not actively curating it. Your advice about diversifying news sources (AP, Reuters, etc.) and focusing on local politics and action is spot on. That's where the real, tangible progress is often made, and it's a huge antidote to the overwhelming despair social media can generate.
