Happy to hear you’re coming home to the Catholic Church!
I came into full communion with the Church through RCIA back in 1983. A wonderful nun was my sponsor though many beautiful and loving members of the Church aided me a great deal as well. I knew I was home as soon as I walked into the Church for the first time and felt the awesome presence of Christ there within the Church. Awesome!!
If you do not have one already. I strongly suggest you get the “Cathechism of the Catholic Church.” I surely would’ve struggled more without it.
In fact, I believe every single Catholic needs to have a current “Catechism of the Catholic Church” in their home.
May The Lord bless and guide you on this journey home.
Peace.
