I just read the “10 Commandments for the Scrupulous” and one of them says that you may not confess sins that you are doubtful of whether they were mortal sins.
I consider myself scrupulous and was wondering if I could receive Communion tomorrow since I have “doubtful mortal sins”. But what if they really are mortal sins?
of course that does not mean that one may not confess them…but one does of course need to say they are doubtful…and if they are doubtful that they are sinful at all…one needs to add other sins that are not doubtful…(but talk with your confessor…for if one keeps wanting to confess doubtful things…it can make a person’s scruples worse…so he may have you not confess such directly …or at least cut it down etc…but that is something to work out with him…and of course he can help you determine to what degree you may or may not have scruples…etc )
…
Now…I do not know you…and I do not want to ask what the sins are…(this is NOT confession!..so no need to say…and I am going to bed soon anyhow…) …but…now if you are doubtful that you gave full consent to …say murdering someone…or committing adultery…or robbing a bank…or watching pornography etc…when you actually physically did these things or other things like them…then i would prob suggest one go ahead and see a priest soon…even if one is scrupulous…
but other sorts of things…well can just be a scruple…
anyhow…
A person with this difficulty really needs to have a regular confessor…if you do not have one…seek one out
As for “doubtful sins” …remember in order to have a mortal sin one needs…grave matter, full knowledge and complete consent…
also remember also…that one is not to receive Holy Communion when one is “conscious” of mortal sin…
it does not say if one “doubts” one committed a mortal sin…do not go to communion…
If you have examined yourself…and you are doubtful that you committed a mortal sin…that would mean by definition…that you are not “conscious” of committing a mortal sin…
I can not judge for you…but certainly do not scruple about anything
(of course if you murdered or something else like the above list

…in which case I would still want to see a priest right quick like…)
And of course you can also quickly see a priest before Mass…but get a R. confessor )
