To any nurses or anyone in the medical field

I’m not sure if this is the correct group to post this in but how did you know that nursing was what you wanted to do? Any advice? How is it? Sorry I’m just curious. My biggest goal for 2020 was to become a mom. My husband cheated and left me. Now I want to be independent and strong. I have decided to go to school to become a nurse. I’m kind of scared but excited. Any advice would be very appreciated ❤️
