I don't think anyone here would tell you to go to police.

Even if they're Neurodiverse, it is no excuse, and they clearly know it, and acting like it is ableist.

I'm not sure on places to host, but having a place to organise thoughts and evidence to send sounds like a good idea. I'm pretty sure there are some links to sites you could put it on in the FOSS section.

I hope you have someone to work on your trauma with, if not there have been some good links on trauma in wellbeing than may provide a starting point for some healing.

I hope the best for you, don't let your past dominate your future.
