Do you enjoy being a Pediatric Oncology Nurse?

I'm in Grade 11 in High School, and have always considered nursing as a career. However, I have always felt this sort of "pull" towards working as a Pediatric Oncology Nurse, maybe at the Hospital for Sick Children (for anyone who doesn't know, that is a nurse who works with children who have cancer). I was hoping if anyone who is currently, or was, a pediatric oncology nurse to please let me know how they enjoyed their job working as a children's cancer nurse, and the ups and downs of it all! I already know the emotional toll this type of job can have on someones life, but I really feel called to work with these sick children and their families. Any help or advice would be great, I just really want to hear from a peds. onc. nurse firsthand :)
