I was sent to an “emotional growth boarding school” in the ‘90s. I wasn’t kidnapped but many of my schoolmates were. A few years later the department of education (can’t remember if it was state or federal) shut the school down after stories got out about the horrific things that were going on there. Kids forced to sit in corners for days at a time, ambulances not being called for kids who had very seriously self-harmed, strip searches (administered by other kids), physical restraints... I could go on. The place had a cult-like atmosphere that was centered on the headmaster and his weird homegrown therapeutic method.
I had nightmares for years afterwards and still haven’t fully come to grips with what happened there.
