How do I find the courage to apologize when I feel guilty and afraid?
Courage to apologize and act now
The past is gone and you can't do anything about it, so don't brood over it. If you hurt someone, have the courage to apologize and be prepared that they may not accept it.
If I have hurt somebody and feel guilty, I should simply have the courage to apologize, and be prepared that the person may not accept my apology, but that's fine.
