My first reaction to your article was surprise that everyone didn’t already think about these things. Maybe it’s because I’m 20 years older than you are and grew up in the 80s, when we drilled hiding under our desks to escape a Soviet nuclear attack. My impression is that you’re struggling with the fact that your sense of security has been shattered, but I don’t know that I ever had one.
This isn’t meant as criticism…I’m just musing. I think I always had the “disaster could come at any moment” mindset you’re finding yourself in now. Combine that with fact that I’m a Type A planner (and a mom!), and yeah…I’ve war-gamed just about all of the possibilities you listed.
Edited to add: When my car is getting low on gas and I’m tempted to wait until the next day, it’s that “You never know when the day before is the day before” thought that makes get it done now.
