I can also relate to your story. My mother was told both me and one of my older brothers had ADHD when we were kids and she put my brother on Ritalin for only one week. She didn't like him being on the meds so she took him off of them and the two of us struggled all throughout school. My brother really suffered as he also has dyslexia. We never saw any doctors for our ADHD after that.
My moms answer to everything is pretend nothing is wrong, I guess she figures everything will just turn out ok somehow.
