Princeton Admissions

What is my best option? Unfortunately my illness significantly affects my academic performance as cognitive functioning is affected negatively. What can Princeton offer to severely mentally ill people or am I aiming too high? Am I able to get into Princeton as a graduate student instead? I only missed about two years worth of high school because of hospitalisation however whenever I returned to school during that period, I still performed well. I function well now, but before I was ill, I was in the top five of my freshman year in high school. It’s just because of this illness I didn’t have a chance to prove myself. How should I go about this?
