On one hand, sure just a meme. On the other, it may not be ADHD that’s causing these symptoms and getting a professional diagnosis will help with treatment regardless of what’s going on.
Unless it's actually detected with some sort of brain scanner, it's all questions / answers.
For example, I don't want to get an official diagnosis, because I don't want it in my medical records, becaus it might impede things, such as getting a driving licence.
Many doctors where I'm from, tried trearing ADHD with antidepressants. Which is like the exact opposite of what's needed.
