The whole point of ADHD being diagnosed is that it has become a problem. Enough of one that people wait months if not years on a list to be assessed and pay hundreds, thousands of dollars for that assessment depending on insurance or lack thereof. And because of the pandemic shortages, a lot of people have trouble obtaining medication or in my case, they had bad reactions to specific types and need to find ones that work without those side effects. I was fortunate. My therapist was neurodivergent and made sure that I got support even before I was formally diagnosed.
