Sit down with the person (or people) you’ve wronged. A confession should ideally be a private, intimate conversation between you and whoever you’ve affected with your actions. Don’t invite more people than you need to – a confession should be a humbling affair, not a chance for you to perform for an audience. Organize a small, in-person get-together with the person(s) you’ve done wrong to.
Prepare to be completely earnest and genuine. For much of our lives, we project certain facades and cultivate certain self-images that reflect how we want to be seen by other people. A confession is no time to worry about these things. Realize that a sincere confession reveals the inner “you.” You can’t make a good confession from a false position of superiority.
Make an admission of guilt. This is the central purpose of your confession – to reveal that you’ve done wrong. Be direct and to the point. Tell the people you have gathered with that you’ve made a mistake that’s hurt them. Tell them that you feel bad about what you’ve done and that you want forgiveness. Calmly and clearly explain what you did, how you’ve hurt them, and why you’re sorry.
Correct any false information or misconceptions. “Confession” implies that the knowledge of your wrongdoing is a secret. So, when you make a confession, you may also need to explain the true course of events surrounding your wrongdoing, especially if you’ve previously lied about what’s happened.
Ask for forgiveness. Be humble and direct. A line like “I’m really, really sorry. I hope you can forgive me” works fine. This should be what you want out of a confession – to get the assurance that you’re forgiven in the heart of the person(s) you’ve hurt.
