I was recently baptized, have only ever had one confession (about a week or two after my baptism) I was ashamed to have committed a mortal sin so soon after my baptism. I plan on going to confession this Saturday. But I feel as if I'm not spiritually ready. I have a very busy day that day, I know I should put the Lord first above all but that day is busy. I feel that I won't be in the right place to truly focus on this confession. Would it be wrong to seriously focus on prayer, reading the bible more, and avoiding sin as much as possible until next week, while abstaining from receiving the eucharist this Sunday? Or should I suck it up and do it this Saturday. I seriously want to stop this sin, but I don't want to rush the confession if that makes sense. I am not using this as an excuse to commit the sin of presumption, as I intend to (hopefully by the Grace of God) avoid committing this sin for good starting now. Please help.
