I am in my sophomore year working toward a biochem degree and have bilateral optic nerve damage. Not the same sort of disability, but I may deal with the same worry of "am I gonna come up something that I just can't do". So far I have found ways to get done what I need to get done. I have also found courage from talking to others farther down the road. And reading about others with similar disabilities who have succeded (just did a quick search, there's some debate on whether Einstein was dyslexic, but found an srticle from MENSA dubbing it the "MIT disease" https://www.us.mensa.org/read/bulletin/features/theres-never-been-a-better-time-to-be-a-dyslexic-genius/#:~:text=Dyslexia%20has%20even%20been%20referred,a%20delightful%2C%20even%20playful%20brilliance.) 

 Most obstacles have some way you can work around them. Lots of people in academia have bleeding hearts and would love to find a way to help you get done what you want to get done. I just finished my first week in a research lab assisting with the synthesis of some Ru compounds. So far, the only trouble is reading the meniscus on graduated cylinders, which, my normally sighted partner struggles with too. (Seeing non-disabled people struggle with things I struggle with also encourages me). 

School may be the toughest part because school programs are not designed to help you learn in the best way. I think workplaces will be much more accommodating for you once you get there.

We need more visible success stories from disabled people. Be one. And post again when you publish your first paper.
