If I may? Your life is your adventure. I think that, having been away for so long, you will see your country in an entirely different light; in a whole new way. Of course, since I am not from the UK, but am moving there, it willl always be a new country for me, but you can always travel throughout Europe. The hard part is not boring your friends with your stories of "life abroad" or seeming ostentious because you have that experience. I know that when I return stateside for my visits, I always feel somewhat odd myself. Best of luck.
