I have to agree with Sammy there. I've just moved from Australia, to the UK for my job at BA, and I must say, the UK is not a place you really want to live if you're used to lots of space and QUALITY OF LIVING like you are in Australia, and the states.
The problem is, you get stuck. Leave the UK and go back to doing some job that you don't really want to do, or stay in the UK and do the job you love, but live in a country that is in a terrible state. What do you do? Either way you're unhappy.
Anyway, just my opinion and how I'm feeling now, you're prolly quite happy anyway.
