I agree with the above that there is likely an office that helps with physical disabilities and medical conditions. I think you should seek out that information before applying to a school and make sure you will feel comfortable.
My university had a medical center on campus, but I went to a very large university that had a DO program. It wasn’t a hospital, just doctors, but anyway it was easy to get medical care, although emergencies would have to go to the local hospital.
Most public places and large institutions have warnings if there will be strobe lights during an event.
If eating on time is a trigger for you, you’ll be happy to know it’s much easier to control your schedule in college than in K-12, but as a freshman you might be behind upperclassmen for choosing classes, but possibly they make exceptions for people with special physical needs.
My guess is there are epilepsy groups that you can talk to people who are in college now and can tell you what it’s like for them.
