I can understand, the part where you are accepting your mistake and seeking forgiveness shows that you are a good human.
This is enough to let this weight go off your chest.
Everyone does some or the other mistake but how many of them have the insight?
You are one of those few.
Wow, thanks! Feel uplifted.
You've realised a mistake on your part, isn't that great? Also, you could confess to the person whom you may have wronged. It might help relieve you of the stress. And everybody makes mistakes. But once we've realised where we went wrong, our next step has to be to ensure that we do not repeat it in the future 🙂
