Hi Heather
I'm not as far along as you - only day 7 today - so I can't really compare. But I have been on cruches since May already (long story!) and also live on my own, so I really can empathise with the whole situation. But I just wanted to say that there is nothing at all wrong with a bit of sympathy, so you can have a whole load of it from me 
If nothing is done for Christmas, so what? The fate of the world does not hinge on it. If it comes to it - postpone Christmas! A place I worked at some years ago, the department said there were altogether too many parties and things in December (it was a sociable place - everyone went to everyone elses) so they decided to postpone Christmas in the department and have it in February when everyone was thinking good weather would never arrive (although, being in the UK, that seems like a reasonable thing to think as it often doesn't
). It was great - Christmas tree, decorations, party and meal - the lot happened in February! Why not plan for a February Christmas party for friends and family? It isn't unreasonable to think you won't be well up to organising it, and people will probably appreciate it more then. And that will give you something to do while you are sitting at home - plan for the best ever February Christmas party!
As for sitting on your own, I don't know about you, but this can be really great time. Look on the positive - you don't have to be sociable! If you want to hang around half the morning in your tatty but much loved dressing gown, then just go for it. I'm in mine as I type
I don't have to conform to the rules of getting up and getting dressed and then doing whatever.... I can do what I want, when I want, and there aren't many times in my life I get to do that. I have been pondering the idea of having a day when I don't ever get dressed! If you want to watch that chick flick at 10 am in the morning (you know, the one that you'd never admit to watching, ever, to anyone) then you can.
I'm making great progress through the Dr Who colouring book my friend bought me for my birthday - you'd be amazed how relaxing it is and time flies.
And if you'd really like to celebrate being on your own, just read a couple of the threads on here about the partners from hell and how much "help" they are. Yes, many people have great family who are a tremendous help, but not all. And besides which, I bet even those with helpful family are truly itching to be on their own for a bit at times too - it's the human condition that we hanker for what we haven't got!
So if "stuff" isn't happening according to the timetable you want it to do - just change the rules. You're on your own. The rules can be whatever you want them to be.
And now, I suppose I really should think about getting myself out of this dressing gown in the next ... say.... hour!
