Scrupulosity is “seeing sin where there is no sin, or mortal sin where there is only venial.” The only real cure is total obedience to one’s confessor. Sometimes scrupulosity is a temporary condition, common to converts and when someone moves forward in their faith and starts taking it more seriously, and simply better understanding what comprises mortal and venial sins is what is needed. But a good confessor would be able to provide the necessary guidance. It is extremely important, if you think you may be scrupulous, that you do not indulge every nerve-wracking question on someplace like an internet forum. Take it to your confessor and whatever he says, do. You cannot go wrong this way. If he gives “bad advice,” he will be responsible for it before God, not you. Don’t seek second opinions and go looking for other advice that may end up contradicting the first and causing you yet more anxiety. That’s MY advice.

It is very common in scruples for a person to feel compelled to seek second opinions and make SURE of this or that. If you find yourself wanting to do this when you know you are scrupulous…well…know it’s the scruples talking and not your common sense.

Scrupulous Anonymous, be sure to check out their newsletter archive. Liguori also publishes a book called “Understanding Scrupulosity” by Fr. Santa which is an EXCELLENT resource.
Also…it may help to remember your feelings mean nothing in relation to the state of your soul. No matter how bad, guilty, or anxious you feel, it doesn’t mean you’ve committed a mortal sin. Moreover, you CAN do something sinful, feel as horrible as if you killed someone, and whatever you did actually be venial in nature. Your feelings can not be counted. Rely on the facts, not feelings, and most certainly not doubts and "what if"s. God would never condemn someone for something THEY weren’t even sure they did. Where’s the justice in that? Or the mercy?
God bless you
