I've been coming back to social media.
But, I'm taking the reins on blocking myself from doomscrolling.
I've got two vibe-coded (thanks Claude) Tampermonkey scripts for X and Insta:

Mastodon is already good with not enabling doom scrolling behaviour. Might do one for Blue Sky as well - that algo feed is better than X, but still far too full of US and other geopolitics.
Otherwise: For Youtube on web, I recommend Unhook.
For Android, I recommend ScreenZen - it can block specifically the short form video sections of Instagram and Youtube.
