I only lived like that from the age of 13-16 - then I got a license and swore I would never be in that position ... I absolutely hated being dependent on anyone for a ride anywhere.
I didn't have a vehicle for 10 years, but I lived right in the city.
I did live in the boonies for 2 years, but without a car? Not a chance.
Kudos to you for being able to do it, I'd go stark raving mad! (And, it's funny, because once I am home from work I don't WANT to go anywhere, but the thought of NOT being able to go? Couldn't handle it LOL)
