Also, if your kids have a relationship with your family, you’re also taking that away from them. If not for yourself, go for your kids.
I hear completely what you're saying Boundaries and caring for your own sanity is paramount I left my family for years to do my healing work then came back but I still need distance What I learned was I had to get past the trauma and that I was selfish to take everything personally It took time for me to see all that though If you need distance it should be respected and accepted but I also understand it's family and you can't get over your hurts (selfish but all healing is) .. it takes time to build in some hardass detachment Sorry that's all over but do what's best for you. Honour you
If you want someone’s opinion, I say go. I don’t know the story, but you can’t let the drama between you & your sister dictate the relationship you have w the rest of your family. They didn’t do anything to deserve that (as far as I know)
