Sounds like you have some bitter personal experience with all this, I'm sorry to hear. It's hard to argue that news is toxic overall, but I think depending on your perspective, and where you get your news from, it can certainly be an unpleasant experience.
I find news tiring in all but small doses, but find that conversations like this can often be tonic. Yet in them it seem we have to talk about things that are in the news.
In another way, I'd probably rather not consume any news at all except for a strong desire to know what is happening on Earth. And what people think is happening on Earth.
I suppose I could satisfy my desires in some other ways, yet it seems so easy to get that "reward signal hit" from absorbing information. It's interesting to think if we're all like "neurons", sort of hard wired to seek gossip and "signal". As if "information" is like sugar in a way.
I feel it is unhealthy to consume news too much tho. Like scrolling through FB, or YT shorts. Somehow it seems "nutritionally empty" like "junk food". I suppose such a feeling must be commonplace in our world where we are certainly saturated with information -- at least compared to the day when the source of all gossip for the town was the general store. Haha :)
