Siblings of narcissists, psychopaths or sociopaths: what's your experience?

My sister is two years older than me, everything was fine when we were younger, just like normal siblings we would fight but we were best friends, but as she got older she got anger and took it out on me, she would hit me every so often when I made her mad but eventually it became every day she would yell at me and hit me for the littlest of things, like one time I was crying and I didn't tell her why so she slapped me multiple times, then she would punch me at the back of the head.

One day she wakes me up at four in the morning and starts yelling at me she pulls me out of my bed and starts punching me yelling I'm going to kill you, you little bitch, I get out of my room and run she pulls my hair then punches me in the face giving me blood nose, she wakes up my other siblings who are now screaming at her to get off of me and to stop I mange to get out of her hold and she goes back to her room I go down stairs and tell my dad as he wakes up at 4 to get ready for work, he tells me to go back to bed and he will talk to her later that day, I have to go to school that day with only a couple of dumps on my head which you can't notice I go home and see her and she acts like nothing happens and when I didn't talk to her she yells at me saying I need to get over it and tries to act like she didn't even do anything she tells my dad a lie about what happened and I also get in trouble for waking the family up with my screaming.

She tells me I'm selfish whenever I don't want her or her friends to use my make-up and don't want to listen to her. Whenever she isn't mad at me she acts like we are best friends again, until she snaps..she has had multiple breakdowns where she has broken door and bowls in the house and whenever my parents try to get her to go to a psychologist she refuses and screams some more.

I'm always her target as I am the closes to her age in where she can get away with it and I won't fight back, because the one time I did fight back and hit her in the face she became more violent. There have been many times where I am left on my floor crying because she has just attacked me and I can't move.
