Thanks everyone. I think the one on one apology/amends is the way to go. How deep I go into the mental causes will depend on the person. Time has certainly helped the regret but it still remains and I need to out it out there, to talk it through, so that I ca get past this.

Anyone have stories/experiences/feedback on making amends? I found that people were very supportive of my sobriety decision and I hope that my making amends will be treated similarly.
