tell me how can i stay rigid?

i'm 15. i've decided i'm not marrying.my parents force me to wear what they wish. i can n't have my own haircut. so i've decided i'm going to do it when i'm independent. according to what i read in my religion i cann't be forced to marry by my parents.but i'm from a conservative family and society. nothing works here. i tried to talk to mom and she said she won't educate me if i had this plan. according to me if a girl is forced she should marry a person who is physically impaired and if she wants a child she can adopt. i'm thinking how to stay rigid on my point. i don't think i could ever marry. it's creepy. and i was shocked when i heard about some planning going on.
