Are there any nursing specialties for people who don't like too much human interaction?
Maybe working alone is impossible, but maybe instead work in a small, more relaxed team environment?
I thought about being a night nurse, but I heard nights are even more hectic than mornings.
Are you looking for less interaction with patients or coworkers?
PACU comes to mind as I would imagine only a small amount of time is spent working with a fully conscious post op pt, however you still will be around other nurses, surgeons, anesthesia providers, etc. Nursing informatics would remove you from patient contact as well, but would require additional education and an interest in computers, technology.
Home health would probably limit coworker interaction but it is one-on-one care with your patients that you see who are often homebound and sometimes appreciate the social interaction that comes with a visit.
I can't really think of any situation where you are mostly by yourself. Good luck in your search! I am mostly convinced that any decent nurse can find a specialty that is a good fit for individual personalities.
