Can't get started on Christmas

I'm doing my annual Christmas brunch for 10-12 people on Christmas morning, plus I still haven't even thought about Christmas shopping for about 6 or 8 gifts I will need to get. I just can't kick myself into gear. I come home after work exhausted and climb into bed after dinner. Yes, I am single. I have two Christmas parties this weekend and I so don't want to go that I'm thinking of coming down with a cold.
