My worst Christmas, which thankfully didn't invove losing anyone (unless by murdering each other!) was the year dd1 was born.
Dh had to work offshore so I'd be alone with a 6mth old, an 8yo and 12yo. I was invited to stay with a v good friend & partner in London so gratefully accepted even though it meant a 600 mile drive.
A few days before we were due to leave ds2 went down with a vile stomach bug. He got over it and all seemed ok. Then two nights before travelling I got the bug and felt like death warmed up. I began to get over it but felt grotty and couldn't decide whether to go or not. We swithered and dithered and then dh said he would drive down with me and fly back to Scotland to go offshore so I decided to go.
We left at 3pm in the afternoon and had a looong trip, with dd1 screaming her head off in the car all the way along the M11/M25 at some stupid time in the wee small hours.
Got to friends and ds1 was promptly sick everywhere - he'd got the bug too. Dh had to leave us and I was beside myself trying to cope with all three dc. To boot, my friend's house was none too clean, inc an incontinent cat, and she had almost nothing to eat so I had to take the dc out to eat and I felt so weak from lack of food. Dd had just started crawling but with the dirt and cat shit, I couldn't put her down so she spent the entire time in her car seat, poor soul.
Friend's partner came back from a trip to Japan on Xmas Eve, went to bed and refused to get up until 3pm on Xmas Day, all the time saying my dc couldn't open their presents until he was there! He got up, the pair of them had some monstrous row and I was cringing in the bedroom, making plans to leave as decently possible.
I did stay on for a little while but then drove home, stopping overnight on the A1M. I missed the exit for the hotel and got lost, driving round the wilds of Catterick in the middle of the night! Almost home I stopped off at the supermarket where ds2 accidentally ran a trolley into my ankle causing such a severe injury it took almost a year to heal properly. When I eventually reached a safe haven I swore I'd never go away for Xmas again, and I never have.
