no buying useless presents which aren't appreciated. - rulehayl
You can always ask people what they'd like for Christmas, perhaps something they've been wanting but won't buy for themselves.
It was weird at first because I always have been a part of Christmas in some way...
That's sad if you've always been a part of it and now you feel weird. Feeling apart from others and weird around people during customary celebrations is not good for us psychologically. We need to feel included.
Apostate Anonymous, welcome to the forum. I'm glad you're having fun this holiday season and ditching the guilt imposed by that dangerous cult.
