I felt the same as you last year when I was a first semester first year. I wish I could tell you that it got better for me and that I changed my mind and fell back in love with nursing, but I will not tell a lie. I too found fundamentals boring, and the CNA work we did in clinicals even more so. I chose nursing out of a love for the sciences and greatly enjoyed my pre-reqs, but I should have majored in bio-chem or something along those lines, because nursing is not really a science, at least not the way I like. I enjoy the disease process far more than I enjoy the person who has it.
Once we started passing meds it got a little better, but not by much, and now I feel like I signed onto a career to come out as a glorified drug administer. Without the drugs, I feel a bit useless. :/ Or worse, like a hospital maid.
The documentation, however, is very important. It can save your butt in a lawsuit. Never
skimp on it.
I wish you luck, and remember, you are not locked into nursing for the rest of your life. You can finish this degree and then go back to school for something else. You don't even have to work as nurse if you don't want to, but the education is valuable regardless
