Excuse me, but have you forgotten the rules? Taking Communion while in a state of sin is a sin. By STATE OF SIN is meant a state of MORTAL sin. We are all guilty of venial sins, and they will not prevent our taking Communion and benefitting from God’s grace to avoid those venial sins in the future. The Old Baltimore Catechism (the precursor to the CCC) taught that the sacraments (all of 'em) were outward signs, instituted by Christ, to give grace. To gain the efficacious gifts of God, the recipient is to be in the state of grace - meaning, no mortal sin. The exceptions are of course, baptism and penance, which clears the slate, as it were, making the soul more receptive to the grace of God. If you are not receiving communion because you are a sinner (venial only) (what, 99% of the time?), you’re missing the greatest beneficence which Christ has given us to gain closeness to Him. Venial sin should NEVER keep you from Communion. Mortal sin must ALWAYS keep you from the Eucharist UNTIL you clean the soul through penance (or, confession, or reconciliation. Whatever)
I suggest you go back to the catechism and re-read the beliefs we share, in this one Mystical Body of Christ.
I will pray for you, for an increase of faith, hope and charity, and for understanding of what is meant by repentance. To ignore God’s Rule is insulting to Him. We can offend Him in so many thoughtless ways, we must be very careful to be faithful in the major issues.
