my parents make me wanna die

I am 15 years old and my parents have been abusing me since I was like 8 or 7. This ranges from them physically hitting me, screaming in my face and getting really close to me + taking my belongings, for example one time my dad took my phone and factory reset it, threatening to beat me even more if I didn't let him have the phone. My brother always looks the other way, telling me it's my fault. I understand he doesn't want to take sides with me in case he gets beat too, which he sometimes does, but it still hurts.

Because of this, I've become extremely suicidal. Ive wrote countless notes, most of which I threw away because I ended up never doing it. I've drank bleach and pills, but only ended up vomiting. I had an argument with my mum today and she beat me. I cried and begged my dad to help but he just said my crying hurt his ears. I'm in my room typing this out considering whether to do it tonight or not. I have no plan at the moment but I genuinely can't see myself living to 18 at this rate.

I know typing out this post does nothing but if anybody can talk to me I'd appreciate it.
