Why are you even still on Twitter?? Especially if it's affecting your psychological health.

HN is 'good' {not 'very good'} for civil discourse.

I would suggest forums - yes, the good ole forum groups - and specific redds, that focus on broader but specific topics that you enjoy - and staying away from those that you don't.

I also suggest building a personalized network of RSS feeds to content that you like, and interacting the writers and other commenters.

Yes. But they're 'boring' compared to rage/race-baiting, pseudo-politicized gated media with masked--and often open--agendas to keep you continuously riled-up to keep feeding The Age of Stupidity.

Hacker News and relevant Subreddits.

Musk's introduction of monetization on Twitter incentivized rage-baits.

Not that it was healthy to use before, but these platforms incentivize posts that keep you engaged so they can print more money.
