Im 62 and was diagnosed 4 months ago. I saw my primary at Mayo, looking for a referral to a Psychiatrist to discuss ADHD with. Instead she gave me the test right then, diagnosed me and got me on ritalin that week, with the caveat that I get a therapist who specializes in Adult ADHD asap.

Which I did. And 1) yay for an amazing GP and 2) she was right, you REALLY need a therapist who specializes in adult ADHD because after you are on your drugs and have clarity for the first time in your life, you need to be prepared for the entirely overwhelming realization that your entire life could have been so much easier, that you could have accomplished so much more, that you could have contributed so much more, been so much more had you ever been diagnosed before you were (for me 62) an adult.

Now, 4 months into this I am still seething about my not being diagnosed. But less loudly.

Please talk to and talk to more and more Drs until you get your diagnosis. There are many organizations on line and groups on FB that cater to adults with ADHD. Dont allow ONE MORE DAY to go by that you will never be able to reclaim.
