Iām a convert from Protestantism as well, but not in RCIA just yet. I found it difficult at first, but start with the Rosary. Make that a habit. Once you get that down, Iād suggest using various medals you may have on that rosary, if any. On mine are a Miraculous, St. Benedict, St. Michael the Archangel, and Guardian Angel medal. Pray the associated prayers on those, one at a time. I also ordered an Orthodox chotki, which is good for when you donāt have the time for a full Rosary.
Anyway, thereās no wrong way, as others have said. Just jump in! In many prayers, thereās a place to state your petition, and this is where I often get really heartfelt. But as you do the organized prayers more and more, they wonāt feel rote anymore, itāll all be heartfelt.
Welcome home!!
