How have they treated you so badly? There's no hot breakfast served for sure, but treated badly? Genuinely interested
I've found ryanair to do what it says on the tin, you'll fly a lot and get paid (mostly) quite well for it .. not many extra frills. The things that gave gone bad I can think of were a late cab once, a sub standard hotel one night, and the twice a year 6 on 3 off, also very poor crew control of late (other companies won't be free of these issues). If it came to leaving though, it will be due to a better option or a desire to try long haul, not because of hatred for the place.
Any Turkish airline as an FO I think will be a culture shock, but whatever floats the boat
