Lord, have mercy on Your handmaiden!
Some of my very best students were "nontraditionals" who came back to school after thay had raised a child, or even several children. Right now, I have two female students in my class who is in her mid-40's (one of them with 7 children!), and they both do very well academically. A few years ago, I taught a Master's student who was in her early 60-s. Don't be afraid, you can do it, with the Lord's help!
