Withdrawing from a PSEO class

I am in 12th grade and and wanting to withdraw from my anatomy PSEO class. This is not because it is too difficult, but because my schedule is too full for me already.

For reference I am taking AP Chemistry, AP Biology, AP Calculus, AP statistics, a required English class (and the anatomy class) this semester.

I am wondering if a W for withdrawal from the anatomy class will look bad to colleges. I have never withdrawn from a class and never intended to as I am interested in anatomy. I just fear that my mental health will be compromised if I do not drop it.
