Same! I made myself years ago a little web app to fetch Wikipedia Current Events, the top n articles of the day (or the week) on HN, and a few subreddits and that's it. I also progressively stopped using Facebook, Twitter, and Instagram. Things are quieter now.

When it's not enough I switch to text browsing via rss and gopher/gemini.

Wikipedia Current Events is very important to make sure that I'm not cutting myself completely off from the world, and after years of using it it's good enough when complemented with the local news from the people around me.
