Well you are at the exact same stage as me Christmas wise.
I've got to get food for Christmas dinner, 5 presents still to buy, (one is homemade so I need to finish the fucking thing),everything to wrap for Christmas plus DD's birthday, food to get for DD's party, deliver some presents for some people.
Been to the girls football this morning now slobbing around putting it all off.
I'm in a minute going to do some lists do each day until Christmas so I will make myself do it.
First off, need to jump in the shower as didn't have time this morning.
Come on onit, you can get in with me 

Will then today buy 3 of the 5 presents, and deliver at least one.
Tomorrow as much food shop as can be done at this point and remaining present purchase and delivery.Work on the homemade item.
Listen, Christmas was always going to be a) a bastard-given what's happened this year and b) potentially a time of year that could sink you-it's so over hyped and over emotional on top of everything else... You have done so so well. One week tomorrow and Christmas is done and things can start getting back the the new normal as far as possible. You've got this, you can do it.
(But also cut yourself some slack-ad's are no joke-it pretty strong medication and if effects everyone differently-make you to do lists, but include, time to rest up-at the top of them).
Good that you have a friend round-that always helps, when I've been
Low, in that it forces me to get dressed at least.
Thinking of you onit-and so proud of all you've achieved so far.
