I think what is important is, you've realized that what you did was wrong, and I think you'll never do something like that again, right? If so, then dwelling on the past is unproductive. No real harm was done, and once you realized that your actions were wrong you changed. The past is something none of us can change, but you can change the future, so it's best to concentrate on that. Don't beat yourself up now. Yes, you deserve to let this go.
