Saya is my sister's middle name and she's out of control.
So she's 14, she is starting college early...I tried to talk her out of it, but she's 14 going on 30. Mash'Allah she is definitely the prettiest of us, she is stunning and she knows it. She keeps getting approached to model and she tells me she's going to model while she goes to school

. My father and his new wife (

) just had twins and their hands are full. My father has always been very busy and continues to be busy, but has more people vying for his attention. My stepmother excludes my two sisters and takes constant vacations during my father's rare free time.
My sisters came to live in my house, but I'm doing a crappy job

. I don't want to be a parent at 19. I am doing an intense program (insh'Allah will be over soon) at an intense school and all my free time is dedicated to their needs. I'm about to start grad school at another intense school in another intense program (University of California--San Francisco, at least I'll be back in San Francisco) and I already feel burnt out. I feel like my sister needs a parent. My aunts are all happy to have them, but they want to stay with me. My sister stays out late, my father buys her whatever she wants.
I try to instill discipline and while my other sister embraced Islam and is practicing it, Saya is so rebellious....Is it just a phase??? Nothing I do seems right for her, she tells me how much I suck constantly...I don't even know if she likes me
I haven't seen my father for like a month and his wife literally acts like my father has no other children, except when company is around. Should I just send my sister to one of my aunts?
