i'm diagnosed with dyscalculia. i'm also diagnosed gifted. hear me out:
i've always been a quick learner since i was little. i could read years above my level, and grasped concepts easily. but i could never focus, and spent most of my time in class daydreaming. eventually it got to the point where in grade 4 my teachers recommended my parents to get me tested for adhd. to nobody's surprise, the results said that i had adhd, dcd, and dyscalculia. however, they also said that i was extremely gifted; especially in math. they explained that even though i could easily understand the math concepts, my neurological condition made it difficult for me to do simple subtraction in my head. basically, i could get algebra and quadratics but not easy subtraction. today, i've found methods to work around my learning differences, and am doing math a year up, but i sure have to work a hell of a lot harder than my peers.
TLDR: i've got dyscalculia but that doesn't mean i'm stupid.
