Molested at school

So when I was in the first grade I got sent special ed class to help with reading and math and to get caught up.and when I got into the classroom there was students from 8th grade to first grade and one big classroom there's probably about 15 students in that class. It was a very dysfunctional classroom students would act out and so would teachers chairs would be flown across the room I once watch the teacher bash a kid's head into a desk over and over again! But the worst part of all would be every Friday they would have movie day when the teachers would turn off all the lights and the teacher and one teacher's aide would be in the back of the room sometimes sleeping and the rest of us kids would be in the front of the room the 8th grade boys would sit next to me and molest me! I told the principal but the principal made me apologize to my molester because he was the star basketball student at that school and told me you don't want to ruin this young man's life do you! What's worse now is that my son who is now three-and-a-half is going to that exact classroom to start preschool next week! I know I'm going to have a panic attack!!
