I know how scary it can be when you've been away from the confessional for many years. I know because I had been away for over five years.
It was after the funeral Mass of my friend's mom that I went "running back". I still joke that it was her mom's first miracle :)
I left the after Mass gathering early so I could go...to say I had a divine urge is putting it lightly.
Ever since, we have been going regularly..for we do not know the hour when we will pass from this earth.
I posted a video for you, by Fr. Peter...it's only a few minutes long and I pray it is helpful.
After my daily rosary, I always say a prayer for those who are in need of this sacrament. Who may be damned because of a mortal sin on their soul. Eternity is a long time..just sayin'. Please, please...go to Confession.
