Should i tell someone about the abuse from my brother?

I’ve been dealing with a lot at home, and I’m not sure who I can turn to. My brother has been treating me horribly, and it’s becoming unbearable. The worst part is that I don’t feel like anyone in my family, including my mom and helper, sees what’s happening or is willing to stop it. Some of the things he’s done, like pushing me or yelling at me for minor things, really feel like abuse.

One incident stands out. I was just trying to take my phone to check something when he got angry with me. He caught me using ChatGPT but not for cheating, it was for studying. I was just checking if my wording was correct for something I was writing. But he thought I was hiding something, so he accused me of keeping it in Safari’s private tabs. I wasn’t; I had it in my hidden folder on iOS 18, which is pretty secure. He’s 24, but he doesn’t know that iOS has this feature. Still, he flipped out and accused me of trying to hide things from him. It felt like he just wanted to pick a fight.

This then led to the chair incident. I was trying to get my phone back, and he pushed me, causing my knee to get caught between the metal part of the chair and the sofa. I ended up with a bruise from it, and I have photos to prove it (I’ll attach them). It was painful, and the whole situation made me feel even more trapped. It’s really hard to explain how this feels, but it seemed like he just didn’t care. All of this over something so small.

And it’s a double standard because if he does something wrong, it’s never treated the same way. For example, he used ChatGPT to help with a university exam, which is cheating, but he didn’t get in trouble for it at all. It just feels so stupid and unfair that he can get away with things like that while I get punished for even the smallest mistakes.

I’ve been told by some people that I should talk to a counselor or report it to the authorities. But I’m scared of what will happen if I do. Would they even believe me? Would it make things worse? I feel like my brother doesn’t even think what he’s doing is wrong, and I’m not sure how to explain it to anyone else.

I’m planning to confide in a friend tomorrow via messaging. I trust him because he kept a secret I told him a week ago, and I’m hoping he’ll help me figure out what to do next.
