Moving from England to Switzerland was extremely difficult. As we had relatives there. Although (I think, I don't exactly know) the move for my Mum was slightly easier due to the fact that two months before her mother (my maternal Grandmother) died. I hope that didn't sound insensitive.
As for me, I've never really had any friends, so the move didn't bother me. It was more of the adjustment of being in a new environment. Different language, sure I can speak some french but my german....it was non existant back then.
Switzerland isn't very far away from England, so we could visit relatives (or they vice versa) whenever we liked.
Then when we moved to New Zealand, it became very difficult for not only myself (as expected) but for the rest of us. We had moved, in reality a day ahead of England. We may never have seen our relatives again. So, whilst I wasn't remotely concerned, it was just new place, difficulty in adjusting generally.
My sister and father were the first to adjust. I didn't really adjust but I was getting help and support, so I felt that I was coping. Mum, well...she hated New Zealand.
Oh dear, that sounds like a biography of my travels doesn't it? May have to retitle this Malte with: "Saft the residentual Snowy Owl's travels' (/joke) or something along those lines anyway.
I face a similar situation, I should be used to moving by now but like I said. I find it extremely difficult to adjust and when I do finally begin to adjust like Switzerland, we move. When I go to University next year, I don't know what will happen.
Oh well, atleast my german has improved since last time I was here in Switzerland.
