I have two sisters. They are very close, and love eachother and are eachother's best friends. They talk every. single. day. They wring their hands constantly because of my personal choices, none of which have been harmful to me, or my kids, and paint everything I do with their negativity brush, and have been doing this for over 30 years, since we were tweens, basically, and probably before even that. We have an extended family site, and the topic of "sisterhood" came up, and they both gushed how lucky they were to have a sister, how they are so close that their husbands say they are almost like the same person, how having a sister is so special and they had the best sister in the world. No mention of me, their third sister. Every year they would have an outing in which they invited all of the first cousins around our same age for a girls' spa weekend, and they never invited me to it. I think they told the cousins that I could not afford it or would not want to come. I would have had a hard time affording it, but maybe I would still have liked to have gone and read a book or done crafts instead of getting waxed or whatever it is they were doing, just to pop popcorn and sit around the fire, etc. in the evenings.

Sorry I digress. But just because they have a mutual narcissistic fan club doesn't mean you are less valuable. I have three "adopted" sisters, one of which is a cousin from another side of the family who have observed my sisters' behavior from afar and never thought it was nice or fair. I have special friends. Your self worth isn't about these people accepting you. I hope you can find a way to get out of this situation, it took me literally decades and took a tremendous toll on my physical and mental health.
