I'm a geologist, basically the core academic discipline for doomsday prepping. I grew up in a place remote enough to consider most "doomsday" scenarios (no running water, electricity, forage/hunt your own food, etc.) summer camp.
My wife was (by education) an archaeologist. She studied contact period archeology, so the resource prioritization and foodways of pre-industrial cultures in the U.S. are smack dab in her wheel house. She is now an active community garden leader, has an successful square foot gardening system in our back yard, etc..
We were both members of a flint knapping club in undergrad. I have drilled literally hundreds of water wells. I have yet to find a mechanical system I can't figure out and fix. I'm a good plumber with a ton of experience deconstructing and rebuilding a wide variety of pumps, electrical, gas, pneumatic, and manual power. I'm a solid electrician, and built my first transformer when I was 10.
I was a junior archery champion multiple years running until my dad blew out his rotator cuff and stopped shooting. I shot with a bow I made myself for the last few years and my dad made me fletch all his arrows for him.
I grew up fishing every day from basically thaw (around April/May) to first freeze (around October) and then ice fishing after that (northern Maine).
I've eaten just about every animal you can eat that won't make you sick. I've foraged for mushrooms many, many times with no improper identifications yet.
My entire family has an extensive history of making our own furniture. I furnished my bedroom in high school out of what I made in shop class and my grandfather's wood shop.
I also keep a minimum of 3 months worth of canned/dry foods in my home at all times, approximately 20-30 gallons of clean, drinkable water, and will be building a gray water system to capture rainwater to irrigate our gardens with next spring.
So yeah, I'd do pretty well. Stay shut in for the first few months while you all kill each other or starve, then clean up the remainder. To that end I keep tabs on multiple places I can find solar and wind power equipment (about a 1.5 hr. drive from where I currently live, yes I can drive an 18 wheeler), multiple sources of drilling equipment to set groundwater wells (know of a half dozen different options for that within half an hour drive), etc. etc..
