I'd advise spending some time in winter in a place before you move there, rural winters are very different, not always worse but different, you can have short days and long nights depending on how far north you are, you can have the sun obscured behind hills and mountains in the middle of the day. Winds can be ferocious and it can rain for days and days. You need to be aware that you won't have some of the same choices in terms of fuel providers, as many rural places do'nt have mains gas and many have overhead power lines so power cuts can be frequent. You do need to be organised and plan ahead, when we lived in a very rural place, if it started to snow or snow was forcast, we'd go shopping, even if we didn't need anything, just to stock up on the basics so as we could sit out being snowed in for a week or two.
Having said all that winters can be great, in town you have grey skies, grey roads, grey buildings, everything just seems wet and grey, in the country theres still colour even when its raining, all the autumnal colours last right into late winter bleaching gradually to pale yellows, just before the new green shoots come through. I like to snuggle up in bed and listen to the wind, feeling warm and safe in my burrow. Power cuts are less fun, so I keep a good stock of candles and camping lights, we have a gas stove so at least we have hot water and food.
There are plenty of rural places that are on main public transport routes and many also have voluntary drivers who can be booked to take people to medical appointments. There are also many small towns and larger villages where there are shops, doctors surgeries etc. People tend to create thier own entertainment and there are often thriving groups for all sorts of things if you want them.
I will move back to a more rural area at some point, busy village life isn't really for me, it can be like the worst parts of living in town and country, personally I couldn't live in a town again, I think it would crush my soul. I've upped sticks and moved so many times and to so many places, it holds no fears for me in a practicle sense and I'm a natural loner so no people dosn't bother me, to many people, thier noise and smells do bother me.
Dont' allow yourself to get caught up in this, from the south =soft, posh and rich, its a load of rubbish and I'd avoid anywhere where that seems the prevalent attitude, because it will ruin a place for you far more than wind and rain.
