Mrs Tarby777 was fine till we got here but had panic attacks in the first week and had serious homesickness issues which she is only now starting to get over, despite us settling straight into a good church and getting to know lots of good folks. She has an infinitely better lifestyle here, with more to do and more friends than she ever had in England, but she still wishes we had never come, and would happily go back to England tomorrow!
Personally, I never looked back... I suppose I rationalised it all in a blokey way, reminding myself that England's in the toilet, overcrowded, the weather is rubbish, and so on. I guess the thing is, you need to remind yourself that nothing has to be for ever and you can always come back to England if it doesn't work out for you over here. At least you will have given it a go, and in old age you won't have all the "what if?" regrets that go with never having done something you wanted to do.
