First of all, I should just say that I will never fault anyone for living where it makes them happy. This is solely about _me_.
Speaking of unspoken constraints, I also _need_ to be in a big city. My rule of thumb is "does it have a subway?" If not, it's probably not big enough. That constraint alone cuts it down to fifteenish cities. Not a hard-and-fast rule, but I grew up on a cattle farm. I know that life isn't for me, at all.
That's what I figured, and that's fine. I'm just a little sensitive because usually when these topics come up it comes off as "NYC is the height of great living."
Just keep in mind that some people might hate living in a small town or elsewhere, but they make do because they have to: they need family nearby as a support structure or they don't have the money and independence to move somewhere like SF or NYC without being on the streets.
You'd make do too if you had to. Suicide isn't even an option for a lot of people, because preparations and privacy are hard to come by, and they might not even have the mobility to make it happen.
I just wanted you to be aware of what advantages you do have, and what things are really a need (food, water, medical supplies and/or medications, shelter, care if you need it) and what aren't. Other than that live the happiest life that is possible for you!
