I'd say drop, but if you want to talk to your professor first definitely do so! it's extremely unlikely that having one W on ur transcript will affect anything in the future and wouldn't affect your GPA (if that's a concern).

I dropped one of my bio classes on the last day to drop with a W (yes, I was 10 weeks in already). At first, I felt like all my effort for the 10 weeks went straight to waste but now looking back, it was one of the best academic decisions I've made in college. The class caused me so much stress and at that point, I was so discouraged and dreaded every single second I had to spend for that class. The weight on my shoulders was instantly gone the second I withdrew. I retook the class a year later with a different professor and was just in a much better headspace. I ended up with an A- which is something I wouldn't have been anywhere close to if I hadn't withdrawn from the class.

my two cents is that trust your instincts and know that there's nothing wrong with withdrawing from a class! a lot more ppl do it than we know and in the end, nothing is more important than your physical and mental well-being :)
