Having second thoughts…

Hi! Im a senior in college about to graduate in May and im so scared to begin my own teaching journey. I don’t know if it’s just anxiety, but i keep having thoughts that teaching isn’t really what i want to do or i won’t be good enough. I’m an intern in a 3rd grade classroom and i love my kids and love working with them but part of me feels like this isn’t my calling. Maybe im just scared to graduate and grow up, but i wanted to reach out and see if my feelings are normal? Is there any advice, books or podcasts that helped you get through the anxiety? Thanks in advance.
