I forgot to confess some sins so I confessed them again to another priest. But then I remembered that I didn't put in some details that could have changed it. Like, for one of them, my partner and I used someone else's item for a project so we could get started (we didn't use them like a pencil, but just for measurments and such) but what I forgot to mention was that we were graded by our participation in doing something. The other one was that I forgot to say I supported a sin. The last one was that my lust may have been rash judgement.
I was going tell my forgotten details to a priest (just a little while ago) but he said that it would not be trusting God's mercy so now I worry if I am despairing of God's mercy. Am I? Must I confess these little details next confession?
