If you went to a quack doctor once and got poor treatment, would that mean that you never will seek medical assistance again from anyone?
If one barber or hair stylist does a lousy job, do you give up on haircuts, or try a different stylist next time? You can tell by looking around that there are good and bad stylists out there, even though they get the same basic training and go by the same hair cutting principles. Same with confessors.
Give your soul a chance to get its regular maintenance, with someone who knows what they are doing. Try again, and you will have pretty good odds of having somebody who understands, cares and offers something to ponder as you go forward.
You wouldn’t give up if your car needed maintenance. You would keep taking it to a different mechanic until somebody knew what to do. Your soul deserves at least that much consideration, and it will last longer than your car!
Also, I asked a priest once how he feels about people coming back to confession after decades away. He said it is one of the most powerful and moving moments of his priesthood, because he can see someone healing, coming back to real closeness to Jesus, to real holy peace. That doesn’t sound like someone who would scold someone for having been away, does it?
Try again.
BUT... The one thing I would caution is that if you go to a confession near a major holiday, the priest and you may feel rushed, because there will be a long line behind you. Better to go in the “off season”.
All the priests I’ve met are not great ambassadors to the Catholic faith. My experience with confession in Catholic school was that it was very much punishment and was treated as such. I was just relieved that I didn’t have to do that again for another year. And very relieved when I got to high school and wasn’t force marched there every Lent.
