So, unless it is unlikely that you will be able to make it to confession again, I’d say no.Anyone who is aware of having committed a mortal sin must not receive Holy Communion, even if he experiences deep contrition, without having first received sacramental absolution, unless he has a grave reason for receiving Communion and there is no possibility of going to confession.
1393 Holy Communion separates us from sin. The body of Christ we receive in Holy Communion is “given up for us,” and the blood we drink “shed for the many for the forgiveness of sins.” For this reason the Eucharist cannot unite us to Christ without at the same time cleansing us from past sins and preserving us from future sins:
For as often as we eat this bread and drink the cup, we proclaim the death of the Lord. If we proclaim the Lord’s death, we proclaim the forgiveness of sins. If, as often as his blood is poured out, it is poured for the forgiveness of sins, I should always receive it, so that it may always forgive my sins. Because I always sin, I should always have a remedy.230
1856 Mortal sin, by attacking the vital principle within us - that is, charity -** necessitates a new initiative of God’s mercy** and a conversion of heart which is normally accomplished within the setting of the sacrament of reconciliation:
When the will sets itself upon something that is of its nature incompatible with the charity that orients man toward his ultimate end, then the sin is mortal by its very object . . . whether it contradicts the love of God, such as blasphemy or perjury, or the love of neighbor, such as homicide or adultery. . . . But when the sinner’s will is set upon something that of its nature involves a disorder, but is not opposed to the love of God and neighbor, such as thoughtless chatter or immoderate laughter and the like, such sins are venial.130
So consider:1457 According to the Church’s command, "after having attained the age of discretion, each of the faithful is bound by an obligation faithfully to confess serious sins at least once a year."56 Anyone who is aware of having committed a mortal sin must not receive Holy Communion, even if he experiences deep contrition, without having first received sacramental absolution, unless he has a grave reason for receiving Communion and there is no possibility of going to confession.57 Children must go to the sacrament of Penance before receiving Holy Communion for the first time.58
The** 1983 Code of Canon Law** indicates that the same requirement applies today. “A person who is conscious of a grave sin is not to . . . receive the body of the Lord without prior sacramental confession unless a grave reason is present and there is no opportunity of confessing; in this case the person is to be mindful of the obligation to make an act of perfect contrition, including the intention of confessing as soon as possible” (CIC 916).
With grave sin on the soul…it is dead…receiving Holy Communion in the Dead State and separated from the Sanctifying…life giving grace of supernatural life…would be like giving food and drink to a dead person…a corpse…nice gesture…looks good…but of absolutely no use to the recipient…because the person is dead. (paraphrasing Father Baron).The** requirement for sacramental confession can be dispensed if four conditions are fulfilled**: (1) there must be a grave reason to receive Communion (for example, danger of death), (2) it must be physically or morally impossible to go to confession first, (3) the person** must already be in a state of grace through perfect contrition**, and (4) he must resolve to go to confession as soon as possible.
