Isn't this rather a sign that the world is simply too complex and should be simplified?

Nah. I’ve had trouble convincing myself that doing dishes wasn’t an insurmountable task. Depression messes with your perspective. Basic, easy tasks seem impossible.

I have that problem too.

But I've learned that dirty dishes stabilize if you let them air dry. They don't even smell bad. Or get moldy. And after soaking an hour or two in hot water with detergent, they're easy to wash.

So then I just need to wash whatever I need for the next meal. And of course, leave enough clean for my wife to use.

BTDT and I'd say no, it's a psychological effect of being overwhelmed mentally, even if you could handle it in better circumstances. Even the most trivial problems become crushing. Even imagined problems.

I'd say that stuff must be simplified, if you want to accomplish anything.
