No, you're not the only 'grinch' out here. In my case, I think it's a combination of things--every year I'm affected by SAD (this year seems worse than usual), I miss my mom (she died in Dec., her birthday was in Dec., my birthday is Dec. & I hate the thought of another year being alone) and the economy. I'm better than I was a couple of weeks ago, so I guess I'm coming out of it.
On the upside, my kids and their families, my sister-in-law and her family will be here for dinner tonight. And I'm better organized than I usually am.
I hope you have a good Christmas in spite of your feelings and a happy, healthy new year.
