I understand that sensory issues can be very frustrating. Have you tried any sensory therapy for him? I have a friend who's son has sensory issues and she has gotten therapy for him. She has said that there is so much that can be done for these issues with different types of therapy. If you haven't looked into that already, maybe that is something you can explore. If you have a diagnosis, I would think the school would have to provide some sort of accommodation. Have you discussed it with the special ed people at school? They might have some suggestions for accommodations that might not make him feel so isolated. Lots of kids have these types of issues, so there should be some sort of model out there that you could learn from.
I'm sorry this is all so frustrating for you!!!
