It's common in nursing to be told by others that you shouldn't be a nurse, and some may even call you a "fake nurse" if you don't meet their standards of what they think is required to be a nurse. The first time I was told I could not be a nurse was by an elderly woman who believed only women could be nurses.
As an INFJ, I’m almost constantly introspective. Today, I was helping with an emergency where one of our wonderful on-call nurses was in a car accident. During my visit with a patient I admitted yesterday who is transitioning towards actively dying, I was in bewilderment in my mind about how comfortable and peacefully patient I am when I’m around the terminally ill and their family.
