It takes a lot of courage to admit your own mistakes and forgive yourself. It's not easy to let go of feelings of guilt or regret, but it's an important part of moving on and growing as a person. It's so wonderful that you were able to come to this realization and put it into practice. I really admire your honesty. You're absolutely right - there's no point in beating yourself up for something that's already happened. The only way to grow and learn is to accept what happened and move forward.
