Hi everyone, this is my first post. Im a nursing student with one semester left before my graduation, so i will be graduating on April 1017. Iam very concerned with my skills. next semester I will be doing leadership but i don't feel confidence about my skill, but Iam not the only one in my class with the same problem. I don't have any medical background, my experience is sandwich maker. I have being at school for 8 years with no stopping and I have never left and class. But the other day I had a substitute professor at my clinical that made me feel like a cockroach, he told me in front of all my clinical classmate that with my clinical skills i would never passed the hesi exit nor the NCLEX, after that I feel disappointed about myself, but I m very optimistic and I don't want this to hurt me even tough Iam very sensitive. Iam planning to take an extra course about IV administration on December vacation. Any advice will be appreciated. Thanks
