AIO to want to move

Hi guys ive a silent member of this thread for quiet a while and thought maybe I could get some advice from you guys. Right know I'm currently a 19 year old college student who has two and half more years left and I'm living with my parents at the moment. As of recently I've made the decision to leave my parents house because living here is genuinely taking a toll on my mental health. Being the eldest daughter I'm the one everyone relies on the most so I'm cooking, cleaning, and taking care of the little children. Now I don't have the means to move just of yet but I do plan on doing so after graduating. But here is the problem: my father says that children have to stay with their paew ta until marriage especially the girls. I have a hard time accepting this because I genuinely don't know how much long I can take living in this toxic household.
