jstme, I am praying for you. Father pls heal and strengthen this young lady so she can perform her college work effectively. Deliver her from all sickness in Jesus' name.
If she has good grades, she has been a good student. Maybe if she talks to the professor and tells them she has been sick for over a week, they will give her a time extension because she has been a good student up to this point. It could be worth a try. I would let someone know if those were my circumstances.
What is she sick with? Maybe some airborne would help. You can get that over the counter in a pharmacy. It is an immune system boost.
