This blog post explains how at the time of my undetected autism, I was punished for traits caused by my autism such as struggling in school. my folks sent me to a Catholic school with literally zero support or no one that knows about autism/ADHD. At the time I was misdiagnosis with ADHD. You can have both but ADHD is not the main diagnosis.
This serves as a lesson to parents that what my folks did to me did nothing but make me even worse.
