I can't resonate with being this paranoid, that's just making it all worse. We all have to die anyway at some point, and something like this won't kill 6-7 (or 8, not sure at this moment) billion people out of nowhere. So unless everyone suddenly turns into zombies, I think you can chill out.
The world WILL survive. If we can survive something like the black plague and other very serious "deathsentences", a coronavirus won't wipe us all out. It's more likely for you to have a plane crash down into your backyard. That should calm you.
