Thanks everyone for the continued responses and suggestions.
Today I received another negative e-mail from the teacher. DS6 can no longer control himself during lunch, music, and gym. He also is frequently sent from class for refusing to do what everyone else is doing.
I am thinking that I am going to end up losing my career. My oly logical solution right now is to quit my job. I feel so helpless. It's really hard because DH is thinking I am overacting but I can't stand by and watch DS6 struggle and become more and more obviously depressed.
Thanks for listening.
