I know the feeling, but I dont get that way until after the holidays are over and it seems like FOREVER until the weather warms up. I try to keep myself busy, and I try to embrace the season for what it is. The way I look at it, if it was summer was all year long, I would not appreciate it. After a long winter, summer is such a treat!
In the fall there are plenty of things to do. Hayrides, apples, peaches, hiking, apple cider, pumpkins, etc. In the winter we try and bake more with the kids. Make homemade bread, and cookies. We take the kids sledding. (Which is more work than its worth, but at least it kills a few hours of the day) The kids go to bed on the early side since the days are getting shorter, and I get more me-time. I picked up my crocheting again, and I started getting movies and shows for ME on Netflix.
Its ok to focus a little on yourself and try to find things that you enjoy doing to get through until Spring. Hang in there!
