I took this exact same journey. It’s rough. Both nursing and nursing school are tough. I think if you are able/capable, empathetic, a caregiver type, like/need variety, and have passion for this job/career. I think you might just be doing to much at once. Those CNA courses are A LOT. There’s a lot of info and they end with 2 tests- a long multiple choice test and a live skills test (which is hard). So, doing your prereqs/nursing classes at the same time could be extremely overwhelming and difficult.
