A Quote of Ven. Leo Dupont on Never Making Peace with One's Sins

I am trying to find a reference which contains an actual quote from Ven. Leo Dupont, which, as I recollect, can be paraphrased as *"... but I have never made peace with my sins."* Is anyone familiar with the complete and actual quote, and can tell me where to find it? Related to this question is https://christianity.stackexchange.com/questions/74067/how-does-the-catholic-church-tell-us-to-do-reparation-for-our-sins-according-to/79902#79902 in which a reference to Ven. Leo Dupont is made.
