IMO you should just be sincere with yourself, Frank, and be satisfied that you made a honest mistake with no malice.
Take the measures that are proper without inflicting aggressive feelings or actions to yourself or any others. That should be enough.
IMO it has to be enough; we can't live our lives carrying grief for honest mistakes that harm no one. We are fallible and we owe to ourselves and to the people that might benefit from our emotional balance not to be shaken just because there was such a mistake.
