Yeah, that all sounds very similar.
Oh shyt this me, especially the end. In elementary school, I would always have my in the books while teachers would lecture. They told my parents I never paid attention but I must be smart because I aced tests. As I got older, i kept having teachers who wouldnt follow text or would have pop quizes on our conversations so my grades dipped. I remeber getting a D one time even though I used a textbook to cheat; the teacher was sick that day and the sub fell asleep.
I didnt start book reading like that until I was junior in college.
Im 30 years now and I only just realized within the last 4 years that I have difficulty learning by listening. Put a book in front of me or show me how its done, and I absorb it.
Where'd you go to be diagnosed?
To be professionally diagnosed you have to go to an audiologist:
