Ritalin and driving

(I have ADD) So today i had what was about my 30th driving lesson and since i was picked up at school i was under influence of ritalin. Spoiler alert: if i would’ve drived alone i probably would’ve killed someone. I find it hard to spread my attention but with my ritalin it was even worse. And then there is my instructor who tells me where to go all the time and i missed 2 exits anyways. I feel like i drive shitty without ritalin but with ritalin its straight up dangerous. I dont understand why because almost everyone on the internet says they drive great with meds. I just dont understand :(
