Assalamu alaikum - I’m feeling disrespected and I need advice

Assalamu alaikum, I’m Rubab, 16F, and I really need some advice because I feel trapped at home. I have two younger siblings: A (13M) and N (9F). I also have a twin sister. Lately my younger siblings don’t show respect to anyone in the house - not me, not even my twin. Whatever I try to say, they ignore me or turn it into a fight. My little sister especially refuses to listen. When she does something wrong and I tell her to stop, she argues, shouts, or starts hitting me. One time I was changing in my room and she opened the door without knocking. I told her to close it because I needed privacy. Instead of respecting that, she asked “Why are you yelling?” and when I asked why she opened the door she refused to listen and started hitting me. She slapped me, pulled my hair, and wouldn’t stop even after I kept telling her to stop. I almost hit her back, but I didn’t. In our family and in Islam, hitting siblings is a big sin, and I didn’t want to make things worse. Afterward she swore at me, made rude gestures, and walked away like nothing happened. She has said extremely hurtful things before like “go to hell” and “I wish you were dead.” I know she’s nine, but those words still hurt me a lot. My brother is a big problem too. He’s 13 and uses religion to judge and control me. I like singing and editing K-pop videos - it comforts me and helps with loneliness and stress. He keeps saying it’s haram and sometimes hits me while saying that. It’s confusing because he has his own channel where he shows his face, so it feels hypocritical. Recently he left hateful comments on my channel: racial slurs about me, insults about my voice, and mocking my favorite idol. He spammed comments just to upset me, and I deleted them because it was hurting my mental health. Another time he was playing a game on the TV and I, who don’t play because Mom warned me about safety, just recorded a short silent clip of the screen on my phone. He immediately yelled that my videos were stupid and I was sinning again, and then he hit me. He slapped the side of my head near my left ear (I already have hearing problems), and I heard ringing. He hit the back of my head too. I told him clearly not to touch me again. I hit him back once to make him stop. After that he flipped me off, called me a b****, and told me to go to hell. Right now I feel exhausted, anxious, stressed, and emotionally drained. I cry alone in my room. I feel depressed and unwanted in my own house. We’re from a religious Asian family, so when I defend myself I’m treated as disrespectful, even when I’m getting hurt. It feels like I’m expected to stay silent and patient while being disrespected and physically hurt. I do find comfort in stories about the Prophet Muhammad (peace be upon him) and his family when my mom tells them - that helps me feel less alone. But the way religion is used against me by my siblings hurts a lot. I’m studying for my GED and planning to move out as soon as I can. I honestly just want peace. I’d like to stay with my grandmother because she is kind and makes me feel safe. I’m not posting this for attention. I’m just hurt, ignored, and tired. I don’t know how to get my siblings to respect me or how to protect my mental health until I can leave. Any advice would mean a lot. JazakAllahu khairan for reading.
