dude!!!!
your in the position i was in!
I lived in perth, opposite side of Australia, im only 18 and took the risk and moved with no family over here
Im young, and i have been working in customer service since i was 14, then supervisor when i was 16.. i got a job with Jetstar
Dude, you have nothing to loose. Follow your dreams and give it all you got, and people told me, your still young, so whatever you choose you give it the best, and if all fails, head back to your family, and kick on! thats if you have to move, which im more than sure all cc are based in Dubai
But hey... big choice, know how you feel dude!
Good luck, follow your heart and take care man.
