I am sorry to hear about your situation, but I congratulate you for aim to become the best of what you can be. You might want to read the following links about medical school and disabilities:

However, you also must be aware that medical schools have also implemented standards for "essential skills and abilities" for been able to become a physician. One of those standards involves motor function sufficient to be able to do a physical examination. Although these standards are slightly different across medical schools, this is one of the obstacles that you will face. I suggest that you do a google search of those terms to get you an idea. These standards are driven by LCME, not specific schools, but they are implemented slightly differently on each SOM.
In contrast, biomedical investigation (i.e.: PhD school) does not have those standards, and you might be much more successful.
