Dear Dave:
The first definition of scrupulosity is worrying about an act being a sin when it is not; thinking venial sin is mortal, or thinking mortal sin is the unforgivable sin. In this context scrupulosity is exaggerating ones sins, making mountains out of molehills, making sins when none exist.
The other definition of scrupulosity, although related to the first, is a religious form of obsessive-compulsive behavior.
It sounds like you are obsessing so much on the dot over the "i" that you have lost sign that the "i" was enough.
The Church teaches we are to confess in "kind and number". It is not necessary to detail each and every sin, but for example, if one shoplifted once each from Sears, Pennys, Target Stores the confession would be: "Forgive me Father for I have sinned. I accuse myself of shoplifting three times." Unless the priest asks you for more details it is a good confession to say only that.
If one does not know how many times the sin was committed, then just say something like "so many times that I do not remember". If the priest insists that you come up with a number, then estimate.
The key factor in your specific example, however, is that regardless of whether or not you gave the priest the number of times you committed the sin, when the priest absolved you, you are absolved unless you were deliberately trying to hide something. It does not sound to me you were deliberately trying to hide anything. Your intention was good.
To confess "I've been a coward in defending church teachings" you might add to it "almost all the time", "sometimes", "most often", or whatever describes your situation.
Specifics are not needed unless the priest ask for them.
What you should do is chill out :)
You confessed your sins without reserve. The priest absolved you. Therefore you are forgiven.
If you have any concerns at all, then follow the straight line formula and let it go at that, as an example:
"Father, forgive me for I have sinned. It has been ____ weeks since my last confession. Since that time I accuse myself of ________ 2 times, _____ once, ____ 100 times, ______so many times I can't remember, and ______ 3487 times. For these and all other sins that I may have forgotten I am sorry for and ask forgiveness."
God Bless,
