welcome to the forum.
I would start by going to the school wellness center and getting checked out.
If by chance your college does not have one, find a doc and make an appointment. It could be anything from needing a new vision script to dehyration, to complex migraine that needs maint meds.
If you are overly stressed, this could also be a factor.
I hope you feel better soon.
