Failed 12th twice already what next?

so spending 9th and 10th in covid made my basics already fucked because back then my family only had one smartphone available at home so no online studies either in 10th did coachings and stuff but 9th was blank so things were pretty hard and after 10th dad met an accident that got us almost bankrupt had to switch to cbse for jee but was admitted into a school that one of dads friend suggested that they'll waiver admission fee 15-20k well on the admission day without even asking I was given regular schooling and little did I know the school was entirely rigged on my first day I come to know I'm the only one who's in the 11th batch also 2 years of complete isolation and I was a quiet kid since the start so I meet my class teacher who's first question was "kya tum brahmin ho? " I was shocked since I belonged to an icse school and this was never what I'd expect a teacher to ask then he started asking me about my gotra and stuff I don't know I stopped going there they called and asked why wouldn't I come I told it's just me and I feel weird so after a month one more student came and I started going in 11th there were two teachers who were good at teaching deepika mam and binod sir infact binod sir was retired from Delhi University he taught physics to us and we liked studying but since wed ask for more of his classes the principal (our maths teacher) fired him idk what it was I stopped going after they fired him because in chemistry the teacher would make us copy paste entire ncert line by line then ask us to copy question ans from YouTube and internet same in maths he'd come and solve one example that's already written in the book as it is then ask us to solve the rest while hed make calls and sign paperwork I decided to buy pw batch but couldn't keep up due to school work to be completed and also half of the course was already ahead so I barely understood stuff 12th me propmote krne ke baad result wale din they threatened my mum and me that if I don't come to school then I'd be kicked out of the school so I started going but the same thing happened this year too I went 2-3 days then skipped they'd humiliate me whenever I went after days so I stopped going entirely and made a deal that if I keep my copies completed then I'm allowed to skip 2-3 days a week well January we were supposed to stay home and prepare for boards but were asked to come and finish practicals and project work because they didn't get it done earlier even during February this was going on while the dm ordered that all schools were supposed to be closed and any student found the school will be fined so they asked us to come in casual wears that was when we came to know this school wasn't ever registered with cbse at all it registered students in the name of the other branch cbse raided that school but we were asked to keep quiet about it or else we won't be allowed to give boards all the fee receipts were asked which had the older names tho in this attempt I got a compartment in maths and was asked by parents and the teachers that I should entirely reappear for 2025 boards first it was supposed to be entirely regular schooling but they said it won't happen because cbse changed some rules so I went through private candidate and it wasn't less that my dad started the construction for the new house the same year being the eldest son I had to stay there most of the times and when I came back I was already too tired for everything that I'd study miserably failed in 2025 in all three subjects cousin suggested nios I passed in 2025 aug but decided to give 2026 boards again this year but till now my health was entirely fucked grade two fatty liver on borderline grade 3 high uric acid extremely low b12 and a lot of deficiencies with extremely thick blood but got this blood test on 14th of feb and this was another problem because now my parents started forcing me to sleep and mum randomly cried on days which entirely fucked my mental health even though my house was on renovation in oct nov dec jan I still Studied but my exams went extremely fucked I couldn't even learn a thing my headaches were so bad I'd blackout randomly anyone who has any tips for this?
