Look into any man's heart you please, and you will always find, in every one, at least one black spot which he has to keep concealed. -Henrik Ibsen, playwright (1828-1906)
Obviously not a member of AA OR Catholic.
AA's text says the 'we simply do not recover until we tell someone ALL of our life story.'
I have found that it is the things that I'm going to take to my grave with me are the things that bother me the most. i.e. We are as sick as the secrets we keep. I recommend telling those secrets to someone you can trust to keep a confidence.
I used to be arrogant enough to believe that my secrets were "different and unforgivable". Yeah, right………
