Then, just be yourself, don't put up a facade. Doing that can be a real strain on you. Just be Real and do the best you can. Maybe talk to someone close to you about it, get your feelings all out. Maybe write to yourself about it, make a list of pros and cons and a plan on how to handle it. I think putting up facades can damage us. Most of us dislike the holidays for all the same reasons, being with people, trying to be nice when we don't feel like it, spending money, fa-la-la and all. You are not alone. I kind of detach from these so-called holidays. Am having a T-Day meal delivered to my door just for me. I will eat it by myself with TV and my cats.
Good Luck!
