Or am I the only one?
I don't know, I just can't get started. Over recent years, Christmas has become more and more of a chore and less and less enjoyable to the point where, this year, I genuinely don't care if it doesn't happen. 
I really don't know what to buy anyone, I don't have anything I want myself, or at least, don't know what there is out there to want iyswim.
Every year, it gets more and more difficult to get the kids to come up with a list and if ever I go out on a limb and buy them something they have not asked for, it is invariably a disaster. For years now, I not only have to buy things for me and dh to give, I also have to buy for the children to give each other, for my elderly parents to give to the children, even sometimes for other family members to give to the children. I wrap everything, I cook everything, I have to organise everything.
I truly don't want to do it anymore.
But I have to, for the children, right?
