Today I went to confession and confessed my sins as usual, however I wasn’t very explicit, I only confessed my sins under so called umbrella terms. In this case, there were some cases where I did not explicit say these sins (which are not usually present in my weekly confession) but were included in the broad statement of sins. I guess you could say that I deliberately wasnt explicit becaise I felt stupid to say them. But on the other hand they were included (broadly) in those statements. Is this mortal sin?
