And moving forward from being sorry
The thing about it is that it’s already done and it’s in the past.
The thing about it is that it doesn’t matter how grevious it is.
You can’t take back your words or undo your deeds or unhurt a person
You can make it better though, by proving that you’re a better person and is starts by forgiving yourself, then, taking responsibility.
Taking responsibility is honestly evaluating the damage and asking yourself:
What can I do to salvage this? Usually there’s something. And it may take time and effort and you may have to wait for an opportunity.
And if there’s nothing you can do, remember that you are human and beating yourself up neither helps you or the situation.
You might simply want to ask “how do I make sure this does not happen again?”
