Not sure if I understand the question, but I’ll give it a stab.
When I hadn’t been for several years, that confession was a awesome, memorable experience. It’s been 7 years since then, and I still consider it as a turning point in my life. I floated through life for days afterwards. The relief of leaving some “big” things behind, of being able to receive the Eucharist again, and just plain grace.
Now I go every 6 weeks or so. Confession is still awesome, but sometimes I don’t feel a whole lot different when I leave from when I went in. I also find that I am usually not as nervous going in, as I was when confession was a yearly event. So I guess it is a trade-off of sorts.
My experience. Your mileage may vary.
