advice for back 2 school

[specimen1]

im getting back to school near the start of september and im pretty unprepared socially and in general for everybody. long story short, last year i was bullied by my old freind group alot and they made rumors, asked girls that i had crushes on them and that i gooned to them and physical problems where i was the victim most of the time and the police got involved. the whole dance class just judged me behind my back because i existed, informed by an acquaintance. i went to summer school because of them because i talked to them in the internet alot and butchered my first semester, they made images, videos, i got publicly humiliated and i just coped by telling my parents and reporting them to the director. my reputation was tarnished afterwards and i had next to 0 active freinds till the end of the school year and i was just sometimes there to fill the gap but never was actually apart of another new freind group because they would humiliate me as well which i didn't like. To cope, i tried to improve socially by making freinds in the internet but i only sticked with my online freind i met 5 years ago this summer, somehow even on the internet i basically have no chance

do u guys recommend isolation and cope with being alone
this might work because theres a mosque close to my school where i can just stay instead of staying in school
