Parents never saw there was an issue. I was mostly "normal" until I started seeing symptoms pop up in the 5th grade. Don't have a guidance counselor but I should probably just ask my dad.
My parents were against it too, even though my 5th and 6th grade teachers both suggested it. Then in High school my guidance counselors highly recommended I get tested.
There was definitely a stigma for mental illness with the boomer generation, I suspect my mom did not want to be associated with a child that has a mental condition.
