Be prepared for it to take time. I retired and left for a new life in France the same day (although we had owned our house here for some time). I had had a demanding job and my first long, quiet, cold French winter was a real shock. I think that it is one of these things that it is hard to prepare for and because everyone who is still working is really envious, you don't get a great deal of sympathy or understanding. It is a big life change, you are bound to get the "what am I for" feelings and you need lots of time to adjust. Five years on, I have got used to it and enjoy my days and the time I have to devote to OH, the garden, walking, my work on the local council, cooking, grandchildren etc. I think the thing I missed most was being part of a team and sharing the ups and downs of the job with colleagues and I enjoy forums as one way of replacing that. The thing that has given me real intellectual challenge has been the chance to keep improving my French and to have reached a level of fluency when I can swap languages almost without thinking about it. A long journey though; I hope it goes well for you.
