It was super hard to go looking for another doc. I gave up in frustration for a bit, but my hubby got on my case because he was so sure I didn’t really have ADD but decided I was going to be in a super bad mood until it was confirmed one way or the other. I got 2 referrals from our marriage counselor for “real” add knowledgable docs. Made first appt, found out my insurance wouldn’t pay, totally got upset, cancelled the appt, made the 2nd appt, and finally got through an assessment. (prolonged by an entire extra week due to leaving the filled out assessment questionaires sitting on my desk at work before driving 30 minutes to another town to get to that total waste of an appt)
Finally, yes, absolutely ADD, referral to Psychiatrist, prescription for meds, beginnings of results after about 6 wks on Concerta!!! Yes folks, there is a light at the end of the tunnel, but it was an emotional roller coaster for me due to how much my self esteem and marriage was riding on the outcome. I think the most difficult thing is not knowing how long the process will be, and therefore, it is so difficult to pace yourself emotionally and manage your expectations.
I am so relieved to be through that process and so grateful to have found a new direction for improvement that’s actually seeming to have results. I’m still so sceptical that somehow it will all just be some awful joke on me, and not make any difference in the end. I guess that’s just my past experience trying to drag me down. Seriously though, I have been able to function better in ways I am only just noticing. Things I didn’t even know I was screwing up, and now that they are happening better I realize – wow there’s another thing that was making things hard! (Like driving my car without people honking at me because my blinker was on for the last 20 miles – wow it’s so peaceful and I can enjoy the song on the radio) This story has only just begun… much more work to be done.
Good luck to all that are trying to get thru diagnosis – I hope you can get some progress in your life too 
DON’T GIVE UP!!
