Thanks for the replies. The weather might have something to do with it, although it was warmer a few weeks ago and then got cold again. I have been a little stressed I realized (we're trying to refinance our house and it's taking a little longer than I had anticipated and the mortgage company keeps asking for more documentation etc). I wonder if that may have anything to do with it? There have been little stressors at work but nothing major so I'm just confused as to why out of the blue. New Years was pretty out of the blue too. We were visiting my husband's family and out for a drive to see what had changed in the old town we had moved from and wham! Out from nowhere.
