minimo - if I were you, as Christmas is so far away I would create a new social life for myself, go to new clubs, take up dancing or a sport, and get yourself involved with a new circle of friends. Take it slowly, and you'll see that as Christmas approaches, events arise that pull you in - do not rely on your children for company - it's clear that as you've been told so early in the year of the plans for each one of them for next year, they are trying to signal to you that they won't be around and hoping that by saying this so far in advance, you don't count them in among your Christmas activities. I can see how you might be sad about this even though you do understand and see their points of view, but now really is the time to widen your social circle and surround yourself with other opportunities if being by yourself is not an attractive idea to you. Another possibility is to start volunteering at your local hospice, or homeless shelter because on Christmas Day you'll be very welcome there dishing out the Christmas lunch.
