One thing is clear, you want to help people and it sounds like you are most connected with working with children. Have you had the opportunity to talk to those in these fields? If not it's always helpful to get perspective. Also understand what is the most important thing for you when choosing your career path. The areas you've listed align so well with each other (PA / Pediatric Nurse, Special Ed Teacher / Early Childhood teacher) that if you happen to choose one of these areas you will have the option to get a sense of what role gives you most connection. Taking one path leads you to another and along the way you realize what you are most passionate about. Best of luck!
