I am 23 years old, married and the mother of a 3 and 4 year old (soon to be 5 at the end of this month). When I started nursing school they were 2 and 3. I think sakura_SN's post is definitely on point, especially since she said she doesn't have kids.
Some important points mentioned:
1. Support system: God Bless my husband, because if it was not for him I know (not think) I couldn't have done it. He helped me clean, cook, run errands, and even took the kids off for me while I studied.
2. Guilt: You are not going to be able to get it all down, but give yourself grace. Don't expect to have a spotless house after you just had 12 hour clinicals and have to come home, put kids in the bed, and study for an exam in the morning. The dishes can wait! At times you will feel like you are the worst mother in world, especially when your kids look at you and say "Mommy, are you going to school again??" It's enough to make you want to cry.
But, you have to remind yourself that you are doing this for them, and they will soon reap the benefits of the sacrifice you made. I feel like at times I missed valuable parts of my children's lives, but then what better time do it then when they're young-heck they won't even remember it when they get 10!
3. Balance: My first semester of nursing school God spoke to my heart about this very thing, and I have always tried to keep this straight: God-first, family-second, school/friends/etc.-third. If you remember to put God first in everything you do, he will help you to keep the other things in line. Through the grace of God, I have never had to miss a Sunday of church to stay at home studying. I need Him more than I need to be a nurse. He has helped me to organize my life where I realize when enough is enough, and when it's time to just close my books and go play with my kids. I mean after you have studied something for 10 hours, when is it enough?
I think women are designed by God to "hold it down," if you know what I mean. In Proverbs 31 it talks about the virtuous woman, and she did it all. She was a wife, a mother, a seamstress, a homemaker, an entrepreneur, a realtor, a manager and still managed to be beautiful!! Is that not us?
I am graduating in May (with Honors) at the top of my class, and was selected by my nursing class to be class president- and still have my sanity (at least I like to think so). My class mates often joke with me about being the only one in my class who hasn't started smoking or isn't on some sort of anxiety/depression medication. God is good! Congratulations, and know that with God all things are possible- I wouldn't dare try to do it without Him.
Pray for me because I am going to add one more thing to list after becoming a nurse- homeschooler. I am going to homeschool my kids! Boy, I am really going to be on my knees then!!! I wish you the best.
