how do i convince my dad to not let me go back to school again?

i'm being severely bullied at school by my past friend group. they've spread a bunch of rumors about me, some of them targeting my insecurities. the entire school watches me differently and because of my absence for weeks, they believe i'm guilty, when i'm really just afraid. i'm diagnosed with gad, mdd and bpd. the more rumors i hear about me, makes me feel like i want to end it. how do i convince my dad to not let me go back to school again? the school i'm currently in offers homeschool/online school and in-person; however, i only have one class most days, sometimes 2, for the max. i've made up my mind to wake up way earlier and study majority of the day, although i don't get any sleep at all.
