@aproposnix Disclaimer: I do not have dyscalculia or dyslexia. My flavor of neurospicy likes learning languages, but/so maybe my experience will be helpful.
There is a method in which you just listen to a new language (starting with the simplest things), it probably suits what you are saying. They call it "Comprehensible Input" - it's described here: https://www.dreamingspanish.com/. The website is for learning Spanish, but the description of the method is in English. 1/2
