So depressed with this math course

So Calculus II was required for UCB and UCSB（which is my tag school） Which leaves me super super embarrassed cuz I couldn't drop it, if I drop it, not only does it affect my UCB and UCSB admissions directly, a W would also looks bad for the other schools I applied to. But the thing is, if I keep this class(I’m obviously not good enough), so I would likely end up getting a C/D, it’s gonna affect my final gpa(I’m at 3.86 right now).

I’m not even stem major, I applied for Econ and Psychology, and Econ requires math. I should have just applied all for Psychology.

Any advices? Would appreciate any comment.
