It has been mentioned above, but I wanted to stress that college classes taken after graduation during a gap year can change your applicant status: Considering a gap year? Read about this student’s experience [took college courses after high school, considered a transfer applicant at many colleges]
I am also of the view that the best route for you is to excel at community college, then transfer in two years. Do not begin until all health issues have been addressed, so that you are able to produce a CC transcript that reflects your abilities. Best wishes.
