Hi Alex, great avatar. You might look up Dr. Barkley U.S. specialist on adhd.
His web site has the “official test/questionaire” and he covers how to use it.
Also he is on utube .. see vids on totally add site.
You might want to try the tedx series of talks on utube for more info.
Best of luck with getting tested and finding a professional pshrink .. sounds like you have one of my lemons. 
cheers and welcome to the partyy
