Having Covid affected my GPA

Hi all,
Are your schools/ professors being more lenient towards students that contracted covid during the semester? Mine are not, I ended up still having to take exams and do assignments while extremely sick and they knew I had covid. I am failing most of my classes, any suggestion as to how to explain to my professors during our meetings that this is not fair. I am in my senior year, I don’t have time or money to retake these courses.
