I failed microbiology class my first time. I was working full time while also taking pharm. It really is about time management and priority. Now I'm in my last semester of nursing school... I see staphylococcus aureus, or escherichia coli every now and then, yes but I just call it bacteria and know I will need antibiotics. The only thing I got out of it was becoming a germ-o-phobe.
Your stepsister was probably taking chem bc the program didn't accept or she didn't have the credits. Bc usually in any program you get the science 'pre or co reqs' out of the way before starting. I agree that starting as LPN gets you faster exposure to working as a nurse, I wouldve preferred going that way
I truly support the fact that you're going to counseling. Having that baggage to carry in addition to nursing school is just gonna make it harder. this underlying issue can't get in the way.
