I think they are two different questions. It doesn't sound like your heart is in your job - maybe worth working out what you really want to do and take steps towards it? Better to be at the bottom of a ladder you want to climb etc.
Also, make sure you actually do want to go abroad, rather than simply escape from your current job.
I've worked abroad and it's hard, particularly in a non-westernised country. You are away from everything you know, amongst people who, however lovely, are very different to you. I cried for two and a half hours once because I fancied a packet of monster munch.
But I wouldn't change it for anything. Good luck with whatever you decide.
