Nursing?

This might be the wrong group for this but, I’m 19 and graduated last year. I didn’t ever think about going to college because I did really bad in high school grade wise and I just figured I wouldn’t get accepted anywhere and I honestly had no clue on what I wanted to go for. But I’ve been thinking about it and I came across neonatal nursing and labor and delivery nursing and I absolutely fell in love with the idea of it and 100% love doing that for the rest of my life. I’m still worried that I’ll have a hard time getting accepted anywhere due to my high school history. Are there any nurses that had a similar situation, if so how did you go about it and what is required. Also if anyone works in this field what are the pros and cons and what is a typical work day like?

I really appreciate any help💖 just trying to make my mom and little brothers proud🥰
