Along the lines of Kizzie's last point--"We can change the holiday from Christmas to 'Time for Me'"--that's what I've chosen to do for years. Mind you, it's easier as I've long removed myself from the remnants of the FOO (2 siblings; some other very distant, also cut-off relatives). Plus I live alone in a somewhat isolated area--but still have some minimal social life around the holidays; but I carefully choose those.
For instance, I studiously avoid kids' Christmas pageants--too EF prone as these were a big source of childhood pain growing up in an extreme conservative offshoot of a mainstream church (the mainstreamers, I've found, are really alright and bear almost no resemblance to the sect that 'uses' the denomination's name to look more mainstream). Okay, so that's one practicality; I just don't go where I know it'll feel yucky, and stick to those boundaries.
The other thing I've done for years is study, and enjoy, all the other sources from which so many Christmas 'traditions' arose. Often called 'pagan' (by the churchies, of course; little realizing that the word wasn't as derogatory as they've made it). The behind-the-scenes stories involve a really impressive set of celebrations that mark the time from October to February--not just the commercial/religious harumphs focused only on Deceber 25 as the grand daddy of it all. It's a season, not a day, and there's some incredibly rich folklore, legend, and alternatives to going with what's thrown out for the masses to consume. A lot has been lost just by the transition from a largely rural (pagan) cycle to the urbanized world of today.
For several years, I had a boon companion who shared my yen for alternative holiday observances. Though no longer a pair, we converse occasionally and those memories of our 'pagan' observances are some of our fondest recollections. Our standard greeting is "Welcom Yule!" (Yule can include what's now called Christmas, but it goes way beyond).
The season" doesn't have to be the standard one with all its guilt-strewn expectations and norms devised by others for you to follow. Nothing against 'em, but if they don't resonate, one can choose not to join the party or, better yet, create one's own take on the season--seasons, really; but I better leave it at that.
Happy Yule!
