Colleagues speak ill of me behind my back and slander me. I was told that I was in a bad mood these days. I think that man is disgusting. What should I do?

There seems to be a saying that as long as there are people, there will be contradictions. This colleague spoke ill of you behind your back and slandered you, so now you know that you are in a bad mood. In fact, as long as you figure it out, it's really nothing. This colleague speaks ill of you behind your back. Pretend you didn't hear him. What can he do to you? As for the person who sent you the message, you should think clearly. What's his purpose? Perhaps the fundamental purpose of these two people is to make you never recover, don't give up, and don't let yourself lose your mind and do anything bad because of one sentence. Let others speak, as long as you are upright and stand up straight, what are you afraid of?
