If anyone needs the reminder, it's fine to celebrate holidays on your own terms. It can be a family thing, or away from them. It can be with friends, it can be alone and meditative if you need that. You aren't beholden to blood or tradition if you don't need it, you can take what works for you and eschew the rest.
You don't need to do holidays the way everyone else does holidays, but I still think it's a valuable to take these days to stop and observe, in your own ways. Use them to celebrate and appreciate those things that light your life in the middle of a long dark winter.
