Stuck With a Tough Online Exam? Anyone Found a Reliable Way Out?

My final online accounting exam is tomorrow morning, but I have been stuck at the hospital all week because my little brother had emergency surgery. I have not slept properly or opened a single textbook. Now I am panicking because this exam determines my whole semester grade. Has anyone here ever needed to pay someone to take my online exam when life completely fell apart? I just need a trustworthy person to step in so I don't fail.
