Why is my life like this?

Ever since I was a little kid I really wanted to have a degree in college or to finish it and become professional. I'm always enthusiastic back then but as I grow older I realized that being a college student isn't cheap. I'm asian and asian parents doesn't easily let their child to move out and be independent (which I always wanted) I lived with my Dad and his family (I'm a daughter of divorced parents) I voluntarily told them that I'm just gonna dropout of school because I can hear them talking about how much money it would cost me to send for school. I asked them that i wanted to be independent but they don't want it because nobody will take care of their child. And now as I was scrolling through my facebook I can see the posts of my batchmates having achievements in the school. It made me insecure. It made me look down on myself. I don't have any achievements. I can't be prout of myself because there's nothing to be proud of. I cant even take selfies because I think i don't deserve to smile. I want to achieve something. Why are they holding onto me? Why am i the one parenting my younger siblings instead of them? WHY CAN'T I JUST GET OUT IN THIS HOUSE?
