Pinkblue, what a horrible situation to be in, and I think it just makes it worse at Christmas, although it's horrid anytime :-(
I was exactly the same, I had an eight week scan and the baby measured 7 weeks and 1 day with no heartbeat. I chose to wait to see if I could mc naturally, not wanting medical interference if I could help it - and I waited 4 weeks and nothing... The placenta kept growing, so I had ALL the pregnancy symptoms, knowing there was no little baby there and it was dreadful. I had morning sickness, sore breasts, my belly was starting to swell etc and it was all for nothing.
In the end I couldn't handle it anymore, and booked in for a D&C. I wish I had done that earlier, as I missed out on another couple of months of TTC while I was waiting, and it was just emotionally draining.
With the D&C itself, it was fine. I was terrified of hospital, so I actually went to an abortion clinic that was very friendly and personable - figuring that they do D&C's all day long and will be experts... I had lunch with my DH after and other than some cramping and bloating, I was fine after with no bleeding. I had cramps for weeks as my uterus went back into shape, and my next period was five weeks after the D&C.
Good luck with whatever you choose to do xxxx
