I have suspected for a few years that I have adhd and finally took the step to get evaluated for an actual diagnosis. Getting the appointment was its own battle (a story for a different time) but I managed it. The first part was an hour interview type session with a therapist. She sent me home with several paper questionnaires, 2 online ones, and a follow up appointment for some in-office quizzes. I had that second appointment last Monday (it was soooo tedious) and it ended with "once your insurance tells us how much you owe we'll call you, then after that we'll compile all your results and give them to you"
The initial therapist DID say it was a 4-6 week turnaround for a diagnosis/result.
