This is totally normal. We spend so much time preparing and anticipating for the holidays that when it is over in 20 minutes, we are a little down. It is a psychological thing. We just all have to get through it. I am still anticipating.... family over for New Year's Day and a week later a Baptism for grandbaby girl, Lily. When that is over, I will get hit with the doldrums I suppose. Oh, wait, there if the trip to Tampa for my grandson's first birthday party. Then I really will be down in the dumps! Smile, you have lots of company.
