sweetteewalls,
I can only speak for myself, but not a day goes by where I don't wish I could undo what I did while drinking. Some days, when I am reminded of the past, it can really do a number on me. All I could do was give my word to my family that I will never go back to that, and to work on what AA would call living amends. I still get questioned sometimes when I go out for extended periods as to whether I was drinking in secret, but I no longer get upset about it, really. I used to get upset, but I can understand their suspicion.
I suspect only time will heal some things, and I hope in time the same will be true for your family.
Take care.
