I'm sorry that it's not worked out for you here, many adjust and thrive, some don't. It's a big call giving up something to come out into the sandpit but you've lost 2-3 years. In the scheme of things, not much really and a tick in the box for life's experience. Hopefully you're single so less hassle factor.
As for resignations, the rate for pilots is around 2.5%. That's it. For an expat airline, that's nothing to be concerned over. The cabin crew rate, however, is a different story altogether!
Good luck in your future career!
