If you don’t mind my asking, what is the occupation you found? And what led you to an ADD diagnosis? (Asking as someone in their thirties who suspects they might have undiagnosed ADD.)
My career has been various applications engineering roles connected with the semiconductor industry.
I used to have misconceptions about what ADHD really is -- that it was about the hyper kids who couldn't sit still or pay attention in class -- and the controversy over drugs that turned them in to calm, compliant little worker bee zombies.
I would encourage you to find a local specialist in Adult ADD and get an evaluation. There are still some misconceptions out there so don't give up searching if they won't take you seriously.
Thankful to have found an occupation where every day brings some new and interesting problem to solve.
