One of the most important aspect of Catholicism is the idea of confessing to your sins and seeking forgiveness.
The more and more I think about this, I think its quite an attractive idea.
It is not because of the fact that you confess and then you have a big chance of the "sin" being relived, but in the sense that you can get whatever it is, really everything off your chest.
yeah, I know you might dislike the part where they make everything into sins that need to be forgiven, but the fact of the matter is, many people really need to share their experiences - in sin manners or otherwise - to ease the magnitude of it.
You need someone to tell you, its alright, its okay and other people do that, have done that etc. But also, you just need to tell someone. Once out, it doesn't bother you much.
I think the whole idea of talking to a psychologist works because of the talking bit, not necessarily needing someone to analyze the substance of what you're talking about. The priests do exactly that. Weekly confessions are weekly "free" psychologist meetings, if you may, although they will prescribe different remedies to "cure/relieve" you of your problems.
Of course the other option will be to talk to friends, the only problem is that they usually have opinions, can be judgemental, or tell others and most important of all just do not listen as much or as well as our other two options.
