First, thank you for sharing your story- it’s always wonderful to hear how God and His family (Blessed Mother, saints and angels) are working in our lives. Here’s a couple things, just my two cents, but here goes:
1.) It is perfectly ok to not be obsessed with dating when you are 13. If you think about it, dating is really supposed to help us determine who we will marry. Looking back, I see now that most of the “obsession with dating and boys” that happened in high-school and even college was very immature, and I witnessed a lot of broken hearts and deep wounds that occured when people rushed into dating relationships. (I’m 21 and a senior in college, fyi, and I have 4 younger siblings, so I’ve witnessed this a lot) I was one of the few girls in my high school who did not date, and I am very glad I made that decision. That’s not to say that all dating in high school is bad, but to have any chance of being a healthy relationship, both people need to be spiritual and emotionally mature.
2.) As far as the whole “what is my vocation in life?” crisis/question that you’re facing- it’s ok

At this point, don’t try to plan your life out, but instead, try to learn about yourself. That includes finding gifts and talents, and developing a disciplined prayer life. If you haven’t read St. Therese’s *Story of a Soul * yet, I’d reccomend it. Also, Jason and Crystalina Evert have some wonderful material for teens about relationships and how God has designed our hearts. I found those to be paticularly helpful during highschool.
3.) Most importantly, go to Mass and Reconciliation frequently. (Daily Mass, if at all possible) Spend time in front of the Blessed Sacrament and just sit there and listen. He’ll show you your vocation in His time, and don’t be surprised if it’s completely different from what you had envisioned! (Take it from someone who was planning to be an opera singer and is now being called to a Carmelite cloister- He can take your life in brand new directions, and it’s much more exciting that way

) And pray the rosary if you don’t already- the Our Lady looks out for her children, as you already know, and I’ve found that she likes to drop hints when she wants me to know something
4.) Don’t stress yourself out about this. Pray that Jesus changes your will so that it matches His. The worry about theoretically getting married but not wanting to be a mother is not important right now, as you are not at a stage where you could actually do either. Just put it all in God’s hands and trust that He’s got a plan for you, and He’ll tell you everything you need to know when you need to know it.
I know that was long, but I hope it helps- hang in there!**
Thank you so much. I’ll continue my prayers and everything, and yes Our Lady looks out for all her children. Maybe Jesus will help me find my true calling, and I have immense faith in Him. Happy Valentines day
