I have been struggling with sins of lust for a long time, I have commited many sins of lust since my last confession, so many, I can remember. I know it’s pathetic but I’m getting better at avoiding it and I am making my confession tomorrow. I know you are supposed to state how many times you commited a mortal sin, but I can’t remember correctly what should I do?
You can estimate, or give an approximate frequency. If you aren’t sure just “several times” or something similar.
You can give an estimate like 4 times/month, practically every day, twice a year or so, etc., for X number of years, since I was this age and now I’m that age, and so on.
