Is It Safe to Ask Someone to Do My Assignment for Me?

I am a nursing student, and this semester has been incredibly demanding with clinical rotations, practical exams, and theory classes all at once. I have not had a single free weekend in months, and my research paper is due in just four days. I have never used any online service before, but I am honestly considering whether I should finally ask someone to do my assignment because I simply cannot manage everything alone. The problem is I do not know which websites are trustworthy or how to avoid getting scammed. Has anyone here used such services and can share their honest experience about quality and originality?
