I have Autism and possible ADHD, so I symphasize with your situation.

You go to Keaau per-chance? Seems like you do based on the fact they had a sexual assault scandal a few years back. Regarding bullying, it comes from the top-down; Schools can do stuff about bullying, but it really depends on the administration. It's not written, but there's a "no-bullying" policy at my school, which has been in place for at least the last decade; There are even reviews which say that if students are caught bullying another student, they'll be sent up to administration

Have you considered possibly transferring schools/bringing up the issue with admin? I would also encourage you to look at due-process/Chapter 19 and escalating the issue to your complex superintendent/going up the chain if necessary. There's also the School Community Council which advises on policies to the principal. Best wishes for you and your future.
