Prenursing advice pls

Hi guys, I’m a 23 year-old Prenursing major having a crisis. My gpa right now is a 2.75which I know is not good. I’ve taken A&P 1 3 times, A&P 2 2 time,microbiology 2 times and chemistry 2 times. A&P 1 and microbiology are bs and chemistry is a C. I’m currently taking pathophysiology and have a b in the class. I’m sure no nursing school will accept me especially with my grades. The college I’m attending right now doesn’t allow anymore retakes so I was thinking of switching to TWU. To start over in an attempt to get all A’s. I’m starting to lose motivation and am also thinking of just dropping out of college altogether. Do you guys think it’s worth it to change colleges and trying to start over ? Thanks !
