When I immigrated to Canada, online ordering was not as ubiquitous as it is now. I needed to ask someone in the elevator where to buy a laundry basket. I had no idea. Come to think of, how on earth would you know? They do not give you a "handbook to Canadian living" when you land on an IM-1 visa.

Bookkeeper. Lawyer. Handyman. Figure all that out, again, as if those weren't hard enough in the first case.

These things are much harder than anyone would reasonably expect. I expected the change of friends, places etc but never occurred to me how hard it'll be to re-learn shopping.
