Hi Deb and welcome
so sorry to hear your son is intense waxing right now. that is so hard, especially when kids are cruel
my son is now 19yo but when he was at school we had a 504 plan in place for him. By law kids with Tourette Syndrome are covered for special accommodations at school
we found being up front about the TS diagnosis and symptoms with teachers and peers was the best way to ensure a better school experience for our son.
here is more info on it from the TSA

I also wanted to encourage you greatly that there are ways to treat tics that dont involve the strong meds with side effects. My son tried meds for a year but the side effects were really worse than the tics. We then started a nutritional program that has really worked for him
I have a thread here discussing what helped him. Hope it will give you some pointers
