You did not graduate faith formation with your reception of Confirmation and Holy Eucharist. In fact, that milestone was neither the beginning, nor the end of any kind. Rather, the reception of these sacraments, especially Confirmation, was a supply stop of sorts along a lifelong journey of faith. In the Sacrament of Confirmation, you had the gifts of the Holy Spirit stirred up and enlivened in your soul to help sustain you through the challenges which this life brings. Every time you faithfully receive the Sacrament of Holy Eucharist, you receive innumerable graces to strengthen your spirit and resolve to follow Christ. Just because one is fully initiated into the Church does not mean they are finished with learning about the Church and her head, Jesus Christ. That task is one which lasts a lifetime.
