Hmm... it sounds like the media sources that you use may be exaggerating information. Not to say that there aren't truly horrible things going on in the world, but I wouldn't say that it's bad enough that the world as we know it will end. Frankly, that's kind of how things have always been. There's always some existential crisis in every generation. And we've never aced a crisis, and we probably never will. But we'll probably crawl our way past the finish line in a kind of half-assed victory. Not the best outcome, but not the worst either.

The problem with comparing things to "how things were like in the past" is that we only remember the things worth remembering. This applies to everything - we only remember the good movies but not the bad ones, the good songs but not the bad ones, the good times, etc. Inherently, comparing things to the past will make it seem like society is going downhill. Not because things are worse now, but just because everyone forgot all the trash that were in the past and only remembered the memorable parts.

Anyways, it also sounds like you may have depression, and it's causing you to let bad news stew for longer than they should. Might be a strange question, but have you talked to a mental health professional about it?
