Do you get depressed in the days leading up to Christmas?

This year and last year I have got quite depressed in the week before Christmas, because I always expect to feel the magic I did when I believed in Santa, but then I get really disappointed when it just doesn't happen.I'm 16 now, and I'm the youngest in my family. So now that I've stopped believing in Santa I feel sad because it is just not as good anymore, and it also saddens me that my parents do not enjoy it as much now that I and my brother and sister are all older. It is truly depressing. Can I feel the same excitement about getting presents that I used to ever again?
