I wish I could provide you with the best answer.
All I know from my personal experiences, is that I was labeled lazy by my parents and that when I had the diagnosis, I was accused of using it as a crutch!
That was very and still is frustrating to me.

Why people are ignorant to ADD/ADHD is because, the healthy grown ups, in my case, parents, refuse to believe that it actually exists.
Since my mother whom I cut ties with, with the help of my T's advice, is narcissistic in nature, she wants to blame all my faults at me.
She doesn't want to excuse me that my mental health condition was the key factor to many of my poor life choices.

I wish you the best.
