Sisters who left their parents’ home without using university - how did you manage, please advise?

As-salamu alaykum. I’m really struggling with this and would appreciate any advice from sisters who’ve done it. I want to start living on my own and be my own person, but my parents believe a woman should only leave the house after marriage. I’m still young and not ready for marriage, and I don’t want to wait that long. Most of the girls I know who moved out did so because they went to university away from home, but Alhamdulillah I’m studying online, so that route isn’t available to me. How did you find the courage to take that step? Did your parents cut you off when you left? Were you able to rebuild your relationship with them afterward? I’m worried about practical things too: do I just find a place to rent and leave quietly? I can’t really tell them because I’m afraid they might lock me in or prevent me from going out - we have security at home and it’s difficult to get around that without confrontation. How did you handle the logistics and the emotional side? To be clear, my parents aren’t abusive - they’re very protective. I want independence so I can grow and live according to my values. Does that mean I have to ask permission to go wherever I want until I’m ready for marriage? In my town most unmarried girls live with their parents; I don’t know anyone who lives alone. Marriage isn’t something I want right now, and staying at my parents’ feels suffocating. Will my mother stop talking to me if I leave? Will I lose my connection with my family? I don’t want that, but I don’t know how to take the step without causing a major rift. Please share honest, practical advice - how did you plan financially, where did you stay, what did you tell your family (if anything), and how did you protect your relationship with them after moving out? JazakAllahu khairan.
