I'm in the same boat - introverted and living in the country. I have tons of human contact because I have a family with whom I live. I spend most of my non-work time with them. I go out to stores, I go to church, I even see friends and extended family on occasion.

Frankly, I have very little difference in the amount of human contact I have now vs. what I did when I lived in a city before the pandemic.

Where you live can certainly influence how much contact there is in your life, but you can be surrounded by people in the country just as easily as you can be a hermit holed up in your apartment in the city.
