The best jobs I have had in my life thus far were far from the best paid - one exception, which I loved, but a GFC killed the company.
I did have one similar to yours, American based company, just wanted a presence and zero support.
I managed a couple of months but it was ridiculous so found another job that paid much the same and kept me interested.
I think overall you did the right thing, not sure I would have gone the teaching route, but that is personal choice :) Enjoy, teaching degrees are kinda fun according to some of my family who have them. I've a couple of diplomas to allow me to conduct specialised classes but full time teaching would not be my gig :)
