Instead of worrying, some positive action on your part may produce good results. You can apologize to the person you wronged, perhaps restoring good relations.
مَهْمَا كَانَ ٱلْأَمْرُ ٱلَّذِي تَنْدَمُ عَلَيْهِ ،‏ فَٱلسُّؤَالُ ٱلَّذِي يَطْرَحُ نَفْسَهُ هُوَ :‏ مَا ٱلَّذِي يُمْكِنُكَ فِعْلُهُ بِشَأْنِهِ ؟‏
