Lick your wounds if you must, and then move on.  What did you learn through that wound?  Do you think you will repeat the same mistake?  In that case, do not move on.  In most cases, wounds serve their purpose.  Please do not aggravate them by fussing with them.  That is the human way, but you are far more than that.  The wounding happened for a reason.  Lessons can be painful.  Learn from them and be grateful for the lesson.  If you have truly learned, no further harm will occur, and growth will take place.  Welcome to Earth School.
