I'm sorry you're experiencing that. Nobody deserves to be treated that way. Sending good vibes to you

Currently reading through Lord of the Rings with my wife. We're on book two. I've been pretty scattered between books lately otherwise, reading Pirsig's Zen and the Art of Motorcycle Maintenance, Erikson's Midnight Tides from his Malazan Book of the Fallen series, and a book of art made by survivors and witnesses of the atom bombs in WWII Japan called Unforgettable Fire. Haven't had the mental willpower lately to sit down and get a good read in, so I've been jumping between snippets of these books.
I'm a therapist in the US who often treats people with ADHD. I'm sorry you're going through this, it can feel like institutional gaslighting and really there aren't robust systems to actually provide resources, just diagnose (and often, inaccurately).
Russel Barkley is an ADHD specialist who offers GREAT resources for managing ADHD. Many YouTube videos and books. If you're looking for tools, I recommend starting here: https://www.russellbarkley.org/factsheets.html
Also, many therapists treat ADHD regardless of diagnosis. If you express wanting tools for executive dysfunction, etc., they'll likely be able to help. (I recommend asking if they do that in a free consult so you don't waste time/money on first sessions just to get a "No, we're treating XYZ instead").
My pleasure! Sending good energy your way.
