I’m a fellow convert. I joined the Church in 2003.
Folks have mentioned, and you already know that the time period you’re going through has a definite purpose: There’s a lot to learn about the Church! And if we’re lucky and blessed-- we’ll continue to learn until we meet our Lord in eternity.
And you are right in realizing that joining the Church is a commitment, so the Church wants its children to have full knowledge of what they are freely committing to.
But If I could throw this out from my own experience: One of the most important aspects I learned from this waiting/learning period was an introduction into spiritual patience. (because it is just an intro) It was a huge eye-opener into how much control I strive to have over **everything **vs how much I want and need to let God lead and help me. I hope that makes sense.
As to the CCC-- I wasn’t required to read it before my Confirmation, but I found that during times of stress, dryness, or any other difficulty-- just reading it became a comforting balm and a reminder of new glory ahead.
Much Peace and Prayers to you,
