Let me describe my situation to everyone:
I committed some mortal sins. I cannot be sure whether I realized at the time of committing these sins that it was mortal, though I did understand that it was a sin.
Some time into the future, I go to church and receive the Eucharist. I do this for a good bit of time, not just once, twice, or even thrice. I did not know when receiving communion with unconfessed mortal sin that I committed that it was at all wrong or sinful to do this. (I’m pretty sure I didn’t know, anyway.) So, later in life I get confession, and confess all the sins I remember having committed. I learned not to get Communion with unconfessed mortal sin in my conscience inbetween getting Communion with these unconfessed mortal sins and going to my first good confession, which was the confession I was previously mentioning. I confessed having obtained the Eucharist while having unconfessed mortal sin on my conscience. That is my situation.
Where am I in the process of gaining back my grace with our Lord? How sinful was all of that situation? What should I do? Please, explain this to me. Thank you in advance. God bless you all.
