Have an emergency kit (see ready.gov for a good checklist). If you survive, such a kit will help significantly in the immediate aftermath.
It’s also a useful kit for a wide array of (more likely) natural disasters.
After you’ve put together your kit, then I agree. You’ve done your prep, nothing else you can control about it, so don’t stress too much about it.
I personally wouldn't be so quick to give up, but to each their own.
