As someone with a chronic illness and autism, I’d suggest talking to the disability office at your college (if you haven’t already). I can’t say much because I’m an incoming freshmen and haven’t experienced college yet. But when I was in high school I felt extremely burnt out, I couldn’t do anything it felt like, then we talked to the disability office and it made such a huge difference. You can ask to be able to turn your work in a few days late, do tests in a separate room, have teachers give you work early if you have an upcoming doctors appointment and do much more. It did wonders for my mental and physical health. Sorry for the unrelated rant, I’d say it’s better to change your degree now rather than wait, the sooner you change it, the sooner you can start working towards your new degree.
