E.B.
You've gotten great advice, and I'll add just one thing. We've moved many times due to my dh's job. Large foreign countries, a small foreign island, big apartments, small ugly apartments, houses, cities, villages - you name it. Often it was scary. Often it was confusing. One time when dh was assigned to Italy I didn't know we had a dishwasher for the first month. It looked like a cabinet that didn't open. One day I bumped against it accidentally in just the exact spot, and it opened and there was a glistening dishwasher! At that same apartment, the only directions we were provided for the strange oven were in Arabic.
But at each place, it helped to do one familiar thing that we enjoyed. Have a glass of a favorite wine (not a new unfamiliar local variety, but our old favorite, just like always). Cook something familiar even if it wasn't a typical dish from the new region we were in. On the strange third-world island, the kids didn't want mangoes or coconut curry, they wanted macaroni and cheese and chicken during those first weeks. They eventually got to appreciate the local stuff and even enjoy a lot of it. But not at first. I put out some familiar pictures and books. New beds in new bedrooms still had favorite blankets and familiar pillows or stuffed animals.
I think that reminds us of what hasn't changed. Yes, the walls are different. So is the traffic, the accents, the laws, the room configuration, the lawn and garden (or lack of), the stores, the people, the landscape, etc.
But what hasn't changed is the family, the love, the people, the traditions, the memories, the things that make your family yours. Find what makes your family strong and focus on that. You may find that it's not suburbia or the big city, not an apartment or a house, not a gas stove or an electric one, not a car or a subway. But it's Grandma's famous casserole that you make every holiday, or the favorite birthday cakes, or the music you listen to, or the stories you read together, or the familiar blanket on the new couch that you cuddle under when watching your favorite movie. Find those things and take them with you to wherever you go.
