I'm a little slow replying, but hope it helps nonetheless.
I've had a bit of the cold feet before each international move. It's because it's a BIG DEAL! There is good reason to feel worried, stressed, etc. You are transplanting yourself from surroundings of comfort, to what could be hard work settling in.
The first time I moved out of the country was to teach English on a rural island in Japan (population 3000, only accessible by ferry). I didn't feel settled there until almost 6 months into it. Not trying to scare you by any means! Just trying to prove that what you're feeling is normal.
Even when you move to a country where language is not an issue, there are cultural things to get used to. The trick is to try and not spend every waking moment comparing what you don't like to how great it is back home. That is an exercise in futility and will only compound your frustrations. Instead, try to find a way to laugh at it, marvel at it, whatever works, and then realize it's different in your new home and get on with life. Sometimes easier said than done
At the moment, I am finding the trick to staying sane on my second small island (though Barbados is quite large compared to my tiny island in Japan) is to leave periodically and get a breath of the rest of the world. Hence my current existence in Europe for the next few weeks
These days, keeping in touch at home is very easy as well. Skype, Vonage, MSN, ICQ, whatever works for you. We brought a voip phone to Barbados and can call home unlimited for extremely cheap. That helps a lot.
And every so often, just have a rant and get it all out. Then have a beverage of your choice and reflect how brave you are to up-and-leave the comfort of home to take on a new adventure. I know I'd have kicked myself if, in 10-20-30 years I looked back and said "I could have gone to live in (insert country here), but I was too afraid"
Go for it, and enjoy!
