You can do it! We found a rental that will accept our 3 (!) dogs, and spent the last 5 months getting rid of all our accumulated crap here in the US! I am now camping out in our nearly-empty house until I fly on Friday. Yes my husband is making less money there, and everything is more expensive, but IMO life is about experiences and the more of them the better! There were many times I felt totally overwhelmed and wavered about the whole thing, and my husband would just say 'We're going'. Now the end is in sight I feel really good about it. My advice, start decluttering now, sell stuff on eBay, Craigslist, FB etc. I waited waaay too long to do that.
Good luck!
