This is me over the last year or two. Anxiety and creeping horror, interrupted sleep and low mood. Ukraine, Gaza, Trump, authoritarianism everywhere...
I try to avoid online news sources, because there's an infinite amount to doomscroll. I use leechblock [1] in firefox to introduce just enough friction to visiting a news site, without hard-blocking them. Because sometimes I still need to know what's going on.
I check the ten minute news summary on BBC Radio 4 as I'm driving to work. Its time-bounded, and pretty reliable imo - although I lean towards a Guardian perspective. Sometimes I hang around for the big interview afterwards, other times I go back to music on a usb stick. Or just drive.
