Now that I think of it I'm not in the mood for Christmas. First, I'm not Christian, so I see the whole thing every time more and more as something unrelated to me as for example, Ramadan. I don't enjoy visiting the most of my relatives, besides some strings of DNA I share little with them. And my family doesn't have a tradition of doing something particularly bonding or special, so there's not much to look forward to.
I wouldn't really care for the things above, but knowing that some people will have at least one special moment in the year with the people they love, makes me think of what I'm missing and is a bit depressing.
