The all-round comms genius that is Helen Reynolds, directed me to the dictionary definition courtesy of Merriam-Webster.
(Doomscrolling and doomsurfing are new terms referring to the tendency to continue to surf or scroll through bad news, even though that news is saddening...)
Sometimes I discover a word and think, 'ooh, I do that'. It's very hard to break away from reading about the various ongoing things that upset or enrage me. Whether it's the economic slo-mo car crash of Brexit, the disgusting levels of government corruption, or the toxic stupidity of covid denialists, there is always more to read. There is always a new grubby revelation. The stupidity bar keeps dropping every time a true believer in a pandemic conspiracy or an ardent Brexiteer opens their mouth.
And I keep scrolling!
