ADHD vs Anxiety

My wife decided a few months ago that she was going to finally talk to her doctor about medication for her ADHD. Well, that doc was the one that diagnosed my wife well over a year ago, but has since left the practice. This past summer, my wife saw her new primary doc, which was the PA of the old doc. When my wife asked about ADHD meds, the new doc asked if she had been tested, my wife says yes. The new doc asks if she's been really tested with a referral... She hadn't. So, my wife meets with a psychologist or similar specialist and she gives her an interview style test, a written test, and a survey for me to fill out. My wife absolutely hated the whole thing. Well, the results came in a few months ago - anxiety, not ADHD. Honestly, I call BS. The survey I completed had no reference to the piles all over our house, the inability to fully communicate, or managing plans. The specialist called me to go over the results as well and I reluctantly agreed that the focus be on anxiety first, with cognitive behavioral therapy, followed by the ADHD. 

The more time goes by, the more concern I have that her issues aren't going to be addressed, and I am going to continue to have way too many things to manage... However, I can't relate to the anxiety or the ADHD to even begin to comprehend how they can be related and how to fix it. 

Lately, the biggest irritation, is my wife will tell me her plans for something and she leaves out key details or parts of the timeline. I retain what she tells me and that's what I have to go by- only to be criticized when I ask why, or how she's going to accomplish things in that order. I recite what she told me and she'll say something like- that's not what I said, or that's not what I meant... But, I actually retain things verbatim, so I know what was said with absolute certainty. 

I fear my patience for ADHD and anxiety won't last long enough for issues to be corrected. Our abysmal love life is a whole other severely frustrating situation full of talk not matching actions.
