Being 18 myself, I know how nerve-wrecking it can be to go. I’ve been trying to go at least once a month now since I’ve recently come back to actually practicing my faith. To be honest, I had A LOT of embarrassing sins to confess. It’s more difficult to get yourself to go than it is when you’re actually doing it. Every time, no matter how many times I’ve gone or told a priest a particular sin, I always break down into tears. Though, that’s just me (uber-emotional xD lol). I’m sure you won’t feel the need to because I’m sure that you don’t have anything that bad to confess. ;D But if you do, don’t feel embarrassed. The priest understands! Sometimes it’s the best place to cry if you really need to since no one else aside from the priest and you know you are breaking down. And don’t worry about being specific. To be honest, the priest doesn’t want to know the details…usually. But if they ask for clarification, it’s not because they are being nosy, they just want to know the gravity of the sins and any circumstances specific to you which would make it either more or less severe. Also, if you are afraid of forgetting sins, making a list can be helpful, but destroy it right after to keep your sins secret. Though, even still I’ve forgotten sins that were on my list simply from losing my place. But if you forget sins, don’t worry about it. Just say after you’ve confessed all your sins that you want forgiveness for all the sins you have forgotten. As long as you didn’t omit a sin on purpose, there is no need to repeat all of them again. Once you remember a sin, just ask forgiveness on your own and confess it the next time you go. The first few times, you might feel bad after leaving because I’ve found that the time I remember the sins I forgot the most is right after I leave the confessional or in the hour or so after. At least, that’s been my experience. But, I’m trying to learn to get over it, and I’m sure you will much quicker than I will.
Also, whether or not you go to a priest you know or don’t know is a matter of preference. I go to whichever priest is available at my parish. Sometimes I go where I can see the priest and sometimes I go behind the veil. Either doesn’t really make a difference to me. Though, it would be nice to go to a priest you know and have confessed to often because they will recognize you(or your voice if you go behind the veil) and they will be able to help you on your own spiritual journey.
If any of this sounds discouraging, I apologize. It was not my intention (I have a habit of discouraging people on accident. I really need to word things better. lol). I just thought it would be nice to get a perspective from someone your own age. I hope you’ll find comfort and peace during and after your confession. It is truly a wonderful thing to be a Catholic and have the opportunity to confess our sins and hear that we have been forgiven.
God Bless!
