Christmas Really Brings Me Down The Most

I'm really trying this year. I said to myself this year I'll just finally enjoy the holiday and behave like a normal person. But I find that everything irritates me, or even depresses me mildly. Only mildly! Still, I was going to exchange gifts with Ellen and actually call them Christmas gifts instead of "Krause Day".
I wonder... is it possible that I've played ol' Ebenezer for so long that I can't stop? "I am become Scrooge, destroyer of holiday spirit."
I think I'll watch SANTA CLAUS CONQUERS THE MARTIANS and see if it cheers me up or just makes it all even worse.
