Thanks all 
Ooh that's the first time I've seen the chocolate emoticon :o
I am on ADs at the moment, which isn't really anything new - particularly in winter as it definitely makes it worse - but normally Xmas is like the light at the end (or in the middle, really :o) of the tunnel IYSWIM.
I think we will have to be on our own this year (me, DH, DCs 8/6) as DH is working boxing day so we can't travel. In fact he's not allowed any time off in December at all and usually ends up doing 60hr weeks so there is no respite for me, I'd be worn out even if I wasn't ill.
Last year we spent a few days at mum's but went to a friend's for most of the 25th (my parents don't really 'do' Christmas and don't like having the DCs run around so it was best for everyone) which was brilliant. I'm sad - and so is my 8yo - that we can't do that this year. Mind you it does make less people to buy for (DCs are easy to buy for, friends not so much!). I guess we will have my parents here but it's quite stressful due to being such a tiny house and them not actually wanting to do anything. House is an utter tip as well, we made some good progress earlier this year but it's just impossible and spirals so quickly.
I like the idea of a wander round town on my own! If I'm well enough I'll do that. :)
I still have a month off, I am lucky that I'm public sector and am only just down to half pay this month so it's not money worries really, but I'm pretty certain I will lose my job eventually as my illness (chronic, not dangerous IYSWIM) is getting worse. I know that if I get signed off for longer, I'll get the "we just have to point out that you happened to be off for Christmas..." talk which I had a few years ago after my second relapse happened to be Nov/Dec.
I'm feeling totally forgotten about by work as well, I know that sounds petulant but it's put a massive dent in my self esteem.
