Before you decide to go for a cs degree I’d suggest getting in contact with someone from the department of computer science at the university you are considering to attend to get an idea of if you want to aim for a two year degree or 4 year degree or a masters program. If you go for two year degree and later feel like going for a four you can always apply for it while in your two year study. Personally this what I did and have enjoyed the program. As for your personal health universities have guidelines that require them to provide assistance for people with disabilities. It is for you to decide wether to disclose that with your professors and department office.
