As an Adult with ADHD, one can really imagine their juvenescence and what it was to be "different." You looked back and realized that you actually had a terrible childhood. You're constantly getting in trouble at school, you have little to no friends, and people tend to criticize you for your condition. If there's someone you should blame for your childhood failure's, it's you. Not for your ADHD condition, but for your lack of realizing it early on. You could've gotten proper child ADHD assessment and treatment, but you weren’t able to acknowledge your difference.
