Do I deserve to Live?

I just checked my marks and it's fucking 53 like WTF... I knew my preparation was very bad and didn't even study some chapters, I attempted 27 questions in which I got 2-3 incorrect cause of silly mistakes and even though I knew it was gonna be bad like I was still expecting around 80 or little less but this is TOO BAD like I hate myself very much for not doing things properly and regret so many things, my brother is in IIT with around 2000 rank so yeah everyone in my family thinks I'm gonna be even better than him like I already told them it was gonna be bad but now that I know it's this bad I can't even excuse myself like there is no fing excuse yaarrr I fuckd up pretty bad and I don't know what to do, I may be the worst son and brother... I wasted their trust, money, and everything else... my boards are coming so past few days I have been studying for it hard like not 100% which I should but yeah still 70% which is bad in my situation but I just fucked up too much like how the f*** would I face them all, with this marks I wouldn't even get 80%tile, I'm EWS but still I wouldn't qualify, my friends and everyone's around me are better by far and here I am... even though I'm from Kota like I was born in Kota. How do I face them all, with this marks I wouldn't even get 80%tile, I'm EWS but still I wouldn't qualify, my friends and everyone's around me are better by far and here I am... even though I'm from Kota like I was born in Kota and lived my life here still couldn't get better. I'm most afraid to face my brother like he's very serious about my studies even though I confessed before exam I wouldn't be able to get this time he said okay do better in boards and next attempt but still try best in this attempt... even from low standards isn't this too low like even he be shocked how low I have been fallen... I was a good student till 10th, and haven't told him my marks since last 6 months but he expects from me which he should and I scored even lower than his lowest expectation like do I even deserve to face his face? How could I... sorry but I'm not gonna die like cause I know this is too trivial to die and I don't wanna also but I don't even know how tf will I face him or anyone else, my pre-boards of chem is tomorrow and then physics and PE and I have to study too but couldn't concentrate on it due to this, like I'm f***ing ashamed of myself that's made this burner account... plz help me yrrrr Dimag ka bhosda ho rakha hai abhi.
