I've dealt with a variety of abusive situations already in my few 16 years, and I'm still hopeless in how to fix them. My first relationship was emotionally and physically abusive and I couldn't force myself to leave for 7 months after I realized. My parents aren't to the level of abusive but they are extremely emotionally invalidating. My older brother, as recognized by everyone in the family, was both physically and verbally abusive to me only, though my mom brushed it off mostly as "being too close in age" (I don't thing age closeness causes people to try to break your arm on a railing but maybe that's jus the me), and he's off to college now. All of those, though, had other people that recognized those was a bad situations and helped me get out or at least supported me throughout.

Now we recently moved a few states over and I'm the oldest with two you get siblings. Before the move, my younger sister would routinely gouge at my little brother with her nails if she disagreed with something and got angry about it. She would always justify it by blaming him and would refuse to apologize. My parents are super strict and I always thought they'd punish her for it or at least force her to apologize, but they never really did anything past saying "don't hurt your little brother." My little brother is very gentle and the most he's probably done out of anger is throw an action figure at the ground so it's painful for me to watch and I try to step in whenever possible. Now with the move, she seems to have turned on both of us. For example, today, she got angry at me in a conversation and kicked both of my shins so hard they bled and gouged her nails down my entire arm. When she came at me the second time with her hand, I grabbed it. She runs in crying, saying I hurt her as I'm sitting in the backyard bleeding in four spots. My mom said that I shouldn't have angered her and was mad at me all day for it and she got off easy. I have two different scars from her getting me in the past and my brother probably has more. I'm the older and stronger sibling and I have no idea what to do about it if I can't defend myself without punishment from my parents.

I also said to my sister that if she tries to hurt me out of anger again I'm done, I'm not going to play the game anymore and I'm not going to continue trying to build a relationship or speak to you and she said "Fine by me" (mind you, this was a day removed from any incident) so talking to her doesn't help..

If anyone has any ideas on how to help me, that would be wonderful. There's a lot more detail I here than I meant to put in, but that felt good to get off my chest.
