That's not even remotely the worst-possible outcome... just the most likely one. Worst possible is the rampant Omicron spread gives birth to a new - more deadly - variant mutation... the virulence of Omicron with a mutation that alters the spike protein to make our existing defenses ineffective... and we are back to March 2020, but with more dead. AND humans are tired and exhausted and not willing to do any preventative measures any more... defeated. THAT's catastrophizing.
The point being, you are making "the world" responsible for your mood, and your perspective on "the world" is focused like a hypodermic needle on all the shit you have no control over. Not only that, you require absolutely no basis in fact or preexisting conditions in order to paint a ghastly canvas for you, alone, to stare at and feel bad about. You do you, man, but I'ma call you on it. this is a bad mood you're choosing which is not "ennui."
