Hello Hunter24,
I see. My personal experience was a bit different than yours. I was really ignorant about my faith and lacked the bare necessities of knowledge to really practice my faith in a decent manner. You were blessed to have the opportunity to go to Catholic school, for what twelve years? That’s great! That’s a great foundation of knowledge I would assume.
I did not have that, all I had was the experience of having lived with my pious grand mother and lived in a close family with my practicing relatives up to the age of nine years old. Then I was sent to America and that was the end of my Catholic education and exposure. I was never even taken to Church by my new family in America - they were too devoted to the American Dollar.
So, I remained for years very ignorant about basic stuff about my faith. I have actually really dedicated myself these past seven years to learning and as I do and receive the Sacraments I am also growing spiritually. Once I had become an independent adult I practiced my faith but very ignorantly, but thanks to God and Our Blessed Mother Mary I did not get lost. I received inappropriately the Eucharist when I was in my early twenties as a friend who I went to church with told me that I could just receive - so I did. I did not go to church every Sunday but I would visit convents, pray, and do what I knew to do. I confessed for the first time when I was 33 years old - the age of Jesus.

It wasn’t that I decided or recognized that I should go to confession, I just happened to be at Lourdes and I saw all the confessionals and I just went. I think Our Blessed Mother Mary had something to do with it.

But, I digress, pardon me.
How old were you when you were confirmed?
What changes were you expecting? After having received a formal Catholic education for so many years, what were you expecting?
Confirmation, like the other sacraments of initiation, marks the beginning of a journey toward deeper knowledge of God. Our Confirmation candidates join us in claiming our heritage. For years to come, they will bear witness to what loving and believing people have handed on to them—all in the Spirit of God.
CCC 1308:
1308 Although Confirmation is sometimes called the “sacrament of Christian maturity,” we must not confuse adult faith with the adult age of natural growth, nor forget that the baptismal grace is a grace of free, unmerited election and does not need “ratification” to become effective. St. Thomas reminds us of this:
Age of body does not determine age of soul. Even in childhood man can attain spiritual maturity: as the book of Wisdom says: "For old age is not honored for length of time, or measured by number of years. "Many children, through the strength of the Holy Spirit they have received, have bravely fought for Christ even to the shedding of their blood.
