So there are more problems at school

But, not with my son...thank god. My son has ADHD with Tourettes cause by stimulant medication that was treating the ADHD. He also has severe anger issues and auditory hallucinations. He sees his psychologist every month and a private counselor who both agree that he should not be treated for the ADHD at this time. I will only make the Tics worse. He is being treated for the others. So now the school is pissed off at me because I have not put him on the medication for the ADHD, they are always complaining that he is very impulsive and disruptive. But yet, the keep him in main stream classes. What am I supposed to do?????
