I guess that further relevant information was that there was always something a bit “weird” about me, and I’ve experienced major disorganization basically since I was old enough to have stuff. 
I had two psychological (IQ) assessments (“gifted” student), and was diagnosed with major depression when I was 16 (I’m 29 now), but no one ever suggested that I might have ADHD (in spite of disorganization, impulsivity, failing out of multiple post-secondary programs, etc.) until I thought of it myself last summer.
