Old school family..help!

My family is very old school. All the women have kids and the men work. I’m 20 years old and my parents won’t let me get a job or go to college. I have to watch my siblings kids all day. (Its basically like the Duggar family). I am very frustrated because it feels like I can’t have a life. I’m left out of everything and I get in trouble if I don’t do what they say. I tried to get a job but they made me quit it. I know I’m 20, I can make my own decisions but I still live at home and they are very emotionally abusive..how they make me feel, makes me suicidal and have no hope.

My boyfriend tries to help me a lot and he said he’ll get me out of here soon. We are planning on getting engaged soon. However, I feel inferior than him. He has a job and in college. I have nothing and I feel less than him. It isn’t my fault though..my family is crazy and I’m stuck here.

What should I do?

EDIT: I’m not allowed to move in with him until we are married..

They are very controlling
