Please.. help me..its very urgent..very urgent....!!?

YOU seem to be Egyptian. Am I right? However, admitting that you made a mistake can be hard to do, but it isn't that hard. You need to be humble first of all. Let them know you made a mistake and move on with your life. i am sure they lie to you too. Will they beat themselves up so much? be strong and try not to mess up NEXT TIME!
