I agree with this so much. I struggled at school from about 16 and it took me six years to complete my degree. Everyone thought I was ADD, but when I finally got myself into therapy, it turns out my dad had NPD and mum was very likely BPD. Their behaviour stressed me out so much, I couldn't cope at school. Once I addressed these emotional issues, my life did a complete 180 and I've never been this consistently happy ever. I think sometimes it's best to try and search for underlying issues first, before just slapping a prescription for ADD/ADHD in every kid's hand.
