I don't like winter in general but Christmas is ok. I try not to put any demands on anyone, and only do what I can, but have worked at a place that closes for a week at Christmas, and that has made it a lot easier, getting an actual holiday for the holiday instead of scrambling to put it together.

You have not failed, you are alive, you are successful at living by definition. If someone at the holidays is making you feel unsuccessful, that's mean. If it's just you feeling it, though, they may not feel the same way. My kids LOVE unmarried aunts & uncles and I loved mine too. You are free to love them without responsibility, more like a friend and that is something kids can really use.

In the end, it's just a holiday - most of us aren't religious, it's a get together time, some presents, a meal. When my kids were up northish, they said winter really was depressing because of the lack of sunlight, they had not realized that was a real phenomenon and were startled by how it made them feel. So be aware you may be feeling worse than usual just because of that, not seeing clearly or objectively.
