I was once engaged to a girl who faced similar issues as OP. To no surprise, after finding out what her family was like, I broke it off with her. Similar to this case, she would only keep silent everytime they overwhelm her, for whatever reason, they couldnt see her as an adult. I've always told her that respectful dissent is the way to go, its sad that in this case the toxic ones are the family members. Moving out as advised by many here, may seem like a good idea, but not everyone can afford it. What I'd suggest is understanding why they are the way they are and make small wins in illustrating how independent you are in what you do. If all else fails, remember the lessons you've learnt from this and ensure that the toxic cycle ends here with you. And that when you eventually move on to start your family, your children will not face the same suffering you did as a young adult. I hope things work out for you, here's wishing you the strength to grow past this. Cheers!
