emc2, I advise you to find a local U3A and/or WI. Both these groups should have kind and interesting people (or our age!) who will make you welcome, plus a wealth of activities which you can join in with if you wish.
In reference to jordana's thread, I truly sympathise. Our DS & only child and his family are 5000 miles away, in California. DS went 21 years ago and wife a year later, and DGC were born there. DH & I have been lucky enough to see them every year and to be part of their lives, but it's hard to be so far away from them the rest of the time. Skype, email, Facebook, and the phone are all helpful, but one thing I do, which I don't think has been mentioned here, is to use the good old-fashioned post to send postcards, cards, letters and small parcels. The children are delighted to get these. Little, regular contcats, all help.
