It's tough going when your reputation is on the line. The ego likes to get you in its grip and tries to get you to do something to get your reputation back, but why? If people are going to judge you, no amount of trying is going to change their minds.
Some people like to validate their points of view, so will take on whatever information or gossip they are given about others so that they can feel warranted for their own behaviour and attitudes. I have had this a lot this past year. I've had a bunch of people judge me and gossip about me and blatantly deceive me, but no more.
