I feel for you, GT. Been there, done that. Hopefully you enjoy your job, and can fill your off hours with things you enjoy doing. Travel and visit interesting places, buy cool souveniers, and read a lot (an ebook that can download books will help a lot if you don't have access to a lot of english material). That's how I handled it.
Just keep smiling and don't let them get you down. It helps (a bit) to think of all the fun stuff you get to do that they miss out on because of their kids.
