Don't feel bad Julien.
I stopped 'doing' Christmas altogether 11 years ago - no family, no friends.
I don't call anyone. I don't go to parties.
I don't buy any gifts anymore.
I don't even wish people Merry Christmas anymore.
I also remember how it was really great when I was a kid too.
But things have just gotten way 'too mental' with it all. Now it even starts way before Halloween, [of which I think there should actually be a law against].
Every year, I just can't help but notice how 'happy' Christmas shoppers are, standing in lines that are way too long, looking hot, tired, miserable, impatient & frustrated, all just to buy things for people they don't really want to buy for, [but 'have to' out of obligation], spending money they don't have on people they don't bother with or just outright avoid the rest of the year.
And that's even before everyone gets together for a supposedly 'joyous feast'.
Seems Christmas is for the stores and advertising agencies now, more than anything else.
Don't feel bad about anything that bothers you, or that you have mixed feelings about, at the very least.
I can assure you that you're not alone.
Sounds to me what you're 'not feeling so good about' is the attitude & behavior of others.
That's my main complaint and trouble with society in general these days - and that's all year long.
