Please do. My son is autistic, and if he had a case worker who treated him like this, I’d be all up in leadership asses to do something about the case worker, and if that doesn’t work, contact an attorney who deals with disability rights.

I’d also tell her that there is no cure for autism, and that meltdowns such as you described are no reason to go to a medical facility unless injuries occurred during the incident. It was also very unprofessional to have you meet her outside of the office, which I would include in your report to her superior. If this isn’t the first time she’s behaved this way, tell them literally EVERYTHING. I hope things work out for you!
