Idk what to do

My (19f) life is falling apart, my father is practically useless as a parent no support emotionally or otherwise, he's also emotionally and psychologically abusive, my brother is a pervert who disgusts me, my mother turned out to be the most toxic backstabbing bitch l've known, since my family is shit I thought I might consider my self preservation but I failed in one of my paper which ties my hands on opportunities, I can't stop crying this was my only way out, I feel stuck, my friends are my biggest enemies who don't give a shit about me, I seriously am considering ending it all, there's no love no support, I starve most of the days as there's no food, I can't take it anymore, l've tried being optimistic but it's just too much and for what? I feel dead, my heart aches. My family paints this picture of a perfect family but they're very toxic and manipulative they scapegoat me into humiliation and shame I can't take this anymore everyone around thinks it's because I'm the bad one but they twist reality as they're narcissistic, I'm exhausted on every sense, l'm treated like garbage by everyone around me that I loved and cared about, l've practically no support system or mentors most of my old teachers were shit too when I opened up and I'm afraid to do so now in college I know nobody cares, there's no kindness or humanness (irl) because if only just one person cared my life wouldn't be where it is now but I still am putting this here because idk maybe I do want to believe

I want to get out and no getting an offline job is not possible as my parents control me into not doing so, how do I open my opportunities as a student, can I redeem myself?
