A few extras:
* You can't exercise, because dogs don't just bark but also chase you, and no one cares or thinks you're the asshole for complaining because you're in the country.
* Daily life is /very/ stressful. Forgot milk? Well, fuck you, buddy, because you're either doing without it or you're making a 50 minute round-trip that costs $8 extra in fuel. Want a pizza delivered? Nope. Chinese? Hahah. Need someone to come out and provide service? Oh, sorry, the first five places on Yelp don't serve your area. Grandma's calling? Sorry, but you're going to have to get used to repeating things not just once or twice but also a third and fourth time because that one bar of signal isn't going to cut it.
* Depression, drug use, and other adverse coping strategies are literally epidemic -- my entire neighborhood of stable working adults where I grew up all ended up on some combination of meth/oxycontin/xanax/antidepressants with alcohol use in excess of anything I ever see at 2 am throughout the nightlife districts of a top 10 US city.
* Oh, do you think you might need to get actual mental help? Well, those handful of upstanding people who aren't addicts are now going to be judging the hell out of you. Most conditions are just you being weak minded or morally inept. And don't even think about talking to someone or others about your thoughts, because that's not something you do. (And if it's sadness, fear, anxiety, or hallucinations, expect to have everyone suggest spurious religious interpretations instead of physical explanations, which, honestly, as a devout Christian, I now find really damaging both to peoples mental and spiritual health.)
* Friendships are forged as a practical proximal matter and not by choice. No one else benefits your mind or academic or professional achievement, and you probably won't share common interests -- you're buddies because Larry's the most likable dude on your block. In fact, even among friends, most people hold a majority of views that you find seriously revolting, and very few people appreciate any kind of artistic or intellectual activity of any kind. Romantic relationships are even less glamorous.
* Did we go over your essentials yet? Oh, wait, that'll be $70/mo for 1.5Mbps DSL that can't stream Netflix. The water bill will be double any reasonable amount and wastewater is processed in your back yard and at your own expense/peril. If you aren't lucky, you may even need your own well. You'll also have to burn trash or contract a company to come take it. Groceries and house supplies cost 30-50% more per quantity, and you have very little to no selection.
* Trash, everywhere. This alone makes me question anyone who thinks mental health is in any way better in a rural environment. It's sick having to look at collapsing, skirtless mobile homes and junk cars and scrap materials strewn across 15 peoples lawns on the way to the gas station. Any "green space" consists of trespassing behind barbed wire instead of a neatly maintained park.
