We all make mistakes. Use yours as an opportunity to learn. You can grow by accepting your mistakes, learning not to repeat them, and moving on in a positive direction.
After you’ve made things right, remember that everyone makes mistakes, and forgive yourself. Personal forgiveness can bring you a lot of relief.
Try to remember that making mistakes gives you an opportunity to improve. Think about the type of person you want to be in the future, and see what you can learn from your mistakes to help you become that person.
If you sometimes bully other people, think of times you have helped or encouraged people. How do you feel after you do each one of these things?
