My experience has been that the more time people spend on social media and/or consuming the "news" (such as FOX/CNN), the more they have these feelings of impending doom.
That being said, some things are far better now and other things have gotten worse. Our social isolation and self-imposed echo chambers are the primary cause from what I can tell.
Social media and mainstream media is pretty much cancer for the mind. I've been unplugged from all the garbage since around 2015, which is around when people seemed to totally start losing their minds. I still get current event updates from friends as they are all still plugged into the hive mind and basically talk about the same things like clockwork.
I've noticed the doomsday type of rhetoric as well. I really just don't see how people can keep eating this stuff up and not get tired of it.
