need advice regarding withdrawing from a class.

i have 5 classes, 4 of em aren't giving me issues, just one i know the time to drop has passed, frankly i'm changing majors next semester so i don't need this class at all, however i understand that if i drop it, i could lose my financial aid, i'm tempted to ignore it for the semester and not stress myself out however i don't want an f on my record, any advice?
