Yes, I'm not thrilled with the cold either but I have started opening the sliding glass doors on my balcony every morning when I wake so the cats can get a moment's outside air. I think "embracing" the cold, if only for a moment or two (I also walk out at sometime during the day to the end of the driveway, look at the sky, etc.) can help. I like to try to stay "balanced" rather than feeling I'm all one way or another (if I have been inside for too many days I deliberately think of a chore or place to go out to also).
