Christmas Spirit

Help!  I am not in the Christmas spirit at all this year!  I have no motivation to go Christmas shopping or put up all our decorations or even listen to Christmas music.  I don't have that feeling I normally get this time of year, even the thought of looking at Christmas lights with my family (which I normally love) sounds kind of blah.  Am I turning into a Scrooge?  Terence has kind of been feeling the same way which is why our lights are not up on our house yet.  It's not that I don't love Christmas time, because really I do.  I'm just not feeling it this year.
