1.  You're allowed to leave.  In some countries, you dissappear if you mention that desire to the wrong people.
2.  There are other greener pastures that are available.
3. You have some resources to put to work for you in your new setting, not the least of which is your intellect and your worldview.
4.  Because of the technology, you don't entirely lose your support system, since cheap phone service and the internet makes the world a much smaller place.  A hundred years ago, if you moved from Europe to North America, it was effectively the same as dying for the folks you left behind.  They did have some mail, though not reliable and 3 month turnaround.  You could go back by boat, but prohibitively expensive.  

I hope to hear about the great things you cook up in the new venue.

Good luck and have fun!
