To Middle Eastern Muslim women: what was your experience leaving a toxic household?

Assalamu alaikum. I feel so lost and helpless because of my family. I’m 27 (F) and I keep feeling pathetic for not managing to get myself out of this situation. For context, I lost both parents by 16 and have been living with my grandmother since. She’s not the sweet, doting granny stereotype - she’s never been welcoming or supportive and is very difficult to live with. If you’ve ever lived with an elderly person who refuses to help themselves and acts spoiled even when they can do things alone, you’ll know what I mean. Even though I strongly dislike how she acts, she isn’t the main barrier. The bigger problem is my uncle, who basically insists that my sister and I stay under her roof. Without going into too much detail, imagine a controlling, narcissistic Arab man who can be violent. My family situation is complicated, and it’s hard to explain how much control they have over my life - not following their rules could put me in real danger. My options feel limited: getting married off, which I don’t want, or moving out, which might bring serious, even life-threatening, consequences. I work full time and earn enough to live independently (so does my sister, who also wants out), but we’re scared of what could happen if we try. If any Muslim Arab women living in a Middle Eastern country have managed to move out safely, what would you recommend? How did leaving turn out for you? Any practical advice - steps you took, people or organizations that helped, or things to prepare for - would be appreciated. JazakAllahu khair for any help or guidance.
