Editred for clarity.
Thank you to all for you kind and supportive wishes xx
I've found wearing the libre helpful. It's certainly shown effects of stress and the carbs I've been comfort eating, but has helped me stay reasonable. In the past I would have face planted into loads of sweets, without limit, but instead I'm just noticing,  recognising triggers and moving on. It would have been so easy to ignore everything and regress without it.
So Christmas panned out:
Xmas eve, bereavement  and birthday
Xmas day for 7.
Can't remember  breakfast,  maybe not any except picking  while cooking.
Lunch was full turkey dinner for 6 and 1 nut roast for vegetarian
Starter was a soup I'd frozen earlier, tomato,  celery and apple flavoured with sherry. Served with bread for carb eaters.
Main turkey (or nut roast), red cabbage and carrot/swede mash, parmesan coated parsnips
(All frozen ahead), green beans, roasted for carb eaters,stuffing balls, pigs in blankets.
Used a version of 
@LivingLightly  walnut and mushroom nut roast. Very tasty.
Much later  Xmas pudding for those that wanted it. Cheese board.
Boxing day, and another birthday!
Can't remember breakfast, if any.
Lunch for 9, (1 veggie) cold turkey,  gammon  ,cheeses,  salad,  pickles including jarred fermented veg.
Dessert was any combinations  of lc jelly trifle with blackberries (which  went down very well with all), Xmas cake, Xmas pudding, birthday carrot cake, gingerbread, mince pies. Cream, brandy cream or custard Editted to add I didn't eat all these, the carb eaters did! I had 2 bites, 1 of cake, 1 of pudding and lots of the lc jelly
Evening was 3 types vegetarian  pastries, served warm, (I did have quite a few) cheeses.
At various times I had white wine, red wine, only small and often watered down. Did try a Baileys Light but has different flavours to the original  and a bit of an after taste of sweeteners.  Think I'll stick to small amount for the original instead, or make my own lc version. . And I got a headache but that could have been anything.
Today
 A bit of a back down to earth day (understatement!),  and we've heard of another imminent bereavement.
Both bereavements will bring a lot of problems after. The problems from the first are starting already.
Controlling what I can
Early breakfast 5:30, some chocolates  and 1 piece gingerbread.
Palmed as much of the carby stuff as I could off on our departing guests
Early lunch, finally a tasty mushroom  and bacon omelette and lc jelly and mouse.
Mid afternoon an lc hot chocolate. First tried the light Baileys in it but not very pleasant. Much better with a splash of the real thing.
Dinner: turkey fricassee  with sherry and mushrooms.  Rice for the boys. Pud was coffee ice cream with 1 chopped up florentine. Red wine
