WOW I'd be worried too... how is it going so far? I agree with Delight.... talk to whomever you need to and see if there are at least two teachers that teach easier, softer whose classes you can take instead? It's requesting "accommodation" for your "disability"... or for your mental wellness/health. If you must, have your mom have a therapist eval and write a note. I think it's worth it...yes it's a tough year because your peers have no respect for anyone else.
But keep in mind the reason others are so nasty is that THEY are not comfortable either--it's new to them too, and they have found that by making fun of others, putting the focus on others, no one is really looking at them.
Give us an update?
