And if you do indeed have a vocation, it will still be there after you complete RCIA. Please, spend this time in RCIA really getting to know and understand the faith. Ask questions and seek guidance from those whom you know and trust.
If I were you, I would try to meet with sisters in your own community, talk with them and learn from them. It will help you to get a better understanding of what religious life really is and is not.
I admire your zeal, but take it from an older, wiser woman- things will always come in God’s time, not ours. We plan, God laughs!!
