It's been much more difficult than I expected, and I was apprehensive to begin with!
However, when things are uncomfortable I tend to fret for a while and then, eventually, take control of my situation. Sometimes you need to go through that period of discomfort to regain control of your life which has seemingly slipped from your grasp without your noticing it.
I regularly leave my home city to work abroad for months at a time. Sometimes it's fantastic. And sometimes (rarely) it becomes a mess.
When it goes well, it's great. New experiences and new people give you a whole new perspective on life. And if it doesn't go great, then it's probably simple enough to go back to your comfort zone and truly appreciate what you have. If it's not easy to go back - was it really your comfort zone?
