My mom's not Catholic, but boy does she EVER try to guilt me into EVERYTHING! It's ridiculous! Unfortunately, she won't change, and I doubt your mother will either. If you go around making yourself crazy for everyone else, all that will do is make you crazy. It will increase your stress levels, etc, which is actually really bad for your heart and health in general. Start now letting everyone know that this is your choice not theirs, and those who try to stress and guilt you the most are practically begging for you to go elsewhere. Also, realize that sometimes being selfish is a bad thing, but sometimes it's just taking care of yourself. (Physically, mentally, emotionally.) That's not a bad thing. Do what you need to do for you. Try to get bf on board, and realize that a big family means you can't see everyone at the very least, and you shouldn't have to be guilted into it. Maybe you could rotate holidays-one family gets each of 3 holidays per year. You, your family, and bf's family. (My family always gets together for 4th of July, so I included that.) Then, each family gets one holiday, and gets to see everyone once a year, but it's not the same holiday. Alternate them every year. That way at least once every three years, you get each holiday off. If families try to guilt you into too much, tell them they won't get their next holiday. Let them know that guilting you into something is not acceptable, especially when holidays are supposed to be about loving one another. Loving someone doesn't mean smothering or guilting, it means looking out for their best for them. Good luck!
