That sounds like harassment, abuse, and discrimination. What she's doing sounds like it could even be considered a hate crime. I'm shocked to hear this is happening to you because you seem like a responsible, motivated, and compassionate person, considering that you're doing a study to help people with ASD.
I think it's imperative that you report this teacher's behavior to the appropriate authority. In most universities, that would be the dean or the department chair. These are the people who have the power to handle the situation in the right way. I would recommend sending an email to the dean and the department chair asking how to officially file a complain about a teacher. You might want to mention that you're being targeted because of a disability and that it has exacerbated certain health problems. You should probably remain vague in this first email because only the people who address these concerns need to know the details. The person who deals with complaints about faculty should take interest in your case, maintain your privacy, and offer you some kind of support. If they fall short of this, you may need to take your complaint to someone in a higher position. You might want to also talk to the person in charge of disability services about this because it clearly sounds like a case of your rights being violated, not to mention that you are being targeted because of your ASD.
In order to be accredited, a university needs to have a way to deal with situations like this one. Unfortunately, this kind of thing is not uncommon. I had a similar (though less severe) experience with a college teacher once. I tried to make a complaint, but I did not know who to speak to and it backfired. Afterwards, I told my dad, a college professor, about it, and he gave me the information above.
Good luck!
