I agree with the others. Going on the trip would be good for you & they should have been
open to giving you the opportunity, but I have to wonder who is paying for the trip? My parents wouldn't pay for me to go anywhere. They haven't since I was in my early 20s. If I want to go somewhere, it's on me financially. If they want me to go somewhere, they would guilt me, but they would never offer to pay for any of my expenses to get there, or while traveling, even if it were for a death in the family. I know a lot of people have it that way with their families, they have supportive parents who would do anything to make sure they do the "right" thing, but not my family. Everything comes down to the bottom-line.
As for cards, it would be nice if they said Dear "family". I notice after the age of 20 or so, people don't consider you the "children" anymore. They expect that you're an adult with your own family, who doesn't receive mail at that address, and that you live on your own at another address. Maybe they will send you a card at your home? It's weird, the dynamics of life, friends, family... I think things are just different these days. My parents lived in the time of cards, now a days, it seems like no one sends them. I may get one from someone older once in a blue moon, sometimes from someone my age but very rarely, but never from someone younger. It's an old tradition. I seriously receive one card a year, if that. No one has my address anymore. I move so frequently.
I can't stand seeing the tabloid news either. I don't know why anyone cares about
an engagement. I couldn't care less. They keep showing her "humble" beginnings on the news, and really, for Los Angeles, it's a very average, or above average home, probably a million dollars for that house. Most people can't afford to own a home in the city...
You really probably should cut them off, they sound toxic. The problem is just that you will end up in your own little world & with the social anxiety, it could be lonely
