Is it normal to hate your step dad and mom?

I am 18 years old, junior at high school, I live with my mother, step dad and younger brother in Istanbul. My mother has been a pain in the ass ever since my dad and her got divorced, and then she married this strange man who has absolutely no social life or anything fun about him. This man and I got along fine when I was a kid but as I grew older and got a teenage's mind and needs, he has been my worst nightmare. He would call me names, comment on everything that I do, thinks he has the authority to act like he's my father. Once I told him he couldn't act like that and that he's never gonna have the authority of a father over me, he got so mad that he always does this funny angry face when I walk around the house. My mom always warns me to be respectful if I tell him that I just don't care, but he can tell me anything he wants. On the subject of my mother... I am such a success both in school and in music. Most of my teaches show me off. She never appreciates those. I want to study abroad but she wants me to stay in turkey. She is overly obsessive about me. She checks in everything that I do, she never trusts me, she beats me up, she curses me and tells me really nasty things, including "I wish you were a stillborn" and "I hope you get raped in the streets and die." I really don't do anything bad. I just study, watch movies, read and occasionally go out with my friends just like a normal teenager. She thinks I am being passive aggressive when say I don't care about the things she says but the truth is I really just couldn't care less. She is past making a statement valid to me ages ago. She just comes to my room every night looking for something wrong, and I just wait there for her to just fucking leave and she doesn't, she keeps staring at me and asks me why cant I just be normal, or something else that I really don't listen to, and then she beats me up if she wants to, I fight back but she is my mother so I don't hit her barely self defense. She is basically just freaking out over losing control. She won't let me do anything for fun, everything has to be done if absolutely necessary. If I want to bake cookies, I am so useless. If I want to sing, im a huge dissapointment. It's not fair that they have so much control over me, once they cut the wifi off my devices and they can cut back on my pocket money too. Please, anyone had anything similar, give me some advice!
