Starting around Thanksgiving everything seems to remind me that I used to actually like the holiday season, but as I've aged I've turned jaded and bitter and everything only reminds me of things that are gone - like my Grandmother's wonderful Thanksgiving dinners, or, hell, my *Grandmother*. Christmas in my home with my family - the home long since sold. Hell, my parents have moved, moved again, and moved *again* since. It seems like each time I visit they're in a new place so I never feel 'home' when I visit them because it may as well be a strangers house since it *is* a strange house to me. No memories, heck, they moved from NY to FL, so the area doesn't even hold memories. And then my b'day - whee, another year older and nothing to really show for it. Each year pretty much like the last, they all blur together - work and sleep mainly. Oh, yeah, Derek's death anniversary is tomorrow. I completely understand why suicide rates spike around holidays.
This is why I personally stopped celebrating holidays several years ago. I might give something to a handful of friends, partly out of the social pressure to not be a scrooge and shackle someone else's buzz, but I don't even send cards to many people beyond my parents. And for any 'lesser' holidays, forget it completely. The only thing they're good for is time off work.
