I used to look at ADHD with scepticism until I met someone who it to a debilitating level. Shared a room with them once at a conference and seeing them in the morning before taking their pills was eye-opening. They were trying to have about 10 conversations at once, switching between them from sentence-to-sentence, every time they sat down to do something they instantly sprang up and started doing something else before springing up and switching yet again to something else, it was exhausting for me and I was just watching.

Whether I believe that the number of people who actually get diagnosed with ADHD is correct, especially in places that have medical systems and cultures like the USA, I’m not sure, but certainly I now see how for some people it can be completely disabling.
