Post-Christmas Depression

I just got back from Texas and I feel a tad bit depressed and sad...........I think I'm going to call it Post-Christmas Depression. Christmas is filled with fun, family, and friends and of course celebrating our Lord and Savior. We had such an amazing time over the weekend getting to celebrate with both our families together and it was wonderful. I must say I am so blessed to have my parents and my in-laws get along as if they had been best friends for ages. I love them all so much and getting to share our time together is just so meaningful. It's also nice to be in Texas again.......although it was FREEZING.....well not actually freezing, but compared to our 70 degree AZ weather...it sure felt like it. But now I'm home and just a tad bit sad as I unpack and get ready for the work week. Back to reality I suppose. Anyone else ever get this feeling after the holidays?!?
