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.

Taxes, bank accounts, grocery stores, buying alcohol, going to the doctor's, and so and so forth. I had to learn how to do these things again.
If one never moved to a very different society there's no way to really empathise how deep these changes go, you uproot everything that was considered your life. The only thing you have left when moving 10000km away for a job is... The job itself.
Not only those. You give up being able to easily meet your family, friends, ... your favorite spot for hanging out is gone and you are in a completely different society, with other ways how things are done.
And then in this case with just two days in you are probably still in some temporary housing.
For staying you need to find a new job, quickly and a new apartment (which is hard without a job and without permanent visa) and when going home you likely will be marked as a loser who couldn't do it.
