First, let me say, God bless you, and welcome home! You may receive Eucharist before you receive the sacrament of Confirmation. However, since the faithful are bound to receive the sacrament of Confirmation “at the proper time” (age of reason), I recommend you speak with your pastor about enrolling in a confirmation program as soon as possible.
Canon law:
Can. 890 - The faithful are bound to receive the sacrament at the proper time. Parents and pastors of souls, especially parish priests, are to see that the faithful are properly instructed to receive the sacrament and come to it at the opportune time.
Canon 842 §2 The sacraments of baptism, confirmation and the blessed Eucharist so complement one another that all three are required for full christian initiation.
Catechism:
1306 Every baptized person not yet confirmed can and should receive the sacrament of Confirmation.123 Since Baptism, Confirmation, and Eucharist form a unity, it follows that "the faithful are obliged to receive this sacrament at the appropriate time,"124 for without Confirmation and Eucharist, Baptism is certainly valid and efficacious, but Christian initiation remains incomplete.
You are in my prayers.
