I was criticized for my poor working ability, and all my colleagues looked down on me and laughed at me. I feel inferior, and I want to die.

Whether you are really excluded or imagined, I think everything happens for a reason, not for no reason, but because you did something wrong first.

Since you have time to be sad, it means that you are still idle. Take time to get familiar with the business and do a good job. Not only does the boss like you, but you are also very confident and proud. Don't feel sorry for yourself.

There is also a situation where you don't do a bad job, but you don't communicate well. You make mistakes in getting along with your colleagues, say things you shouldn't say, and do things you shouldn't do. That is the lack of your own emotional intelligence.

No one has ever taught us how to behave in school. We learn from our own families and people around us. If you feel that you can't speak and do things, you should learn this ability to make up for this deficiency, instead of avoiding self-pity.

Generally speaking, people still look down on you, or can't see that you don't pay attention to you at ordinary times. I made them myself. Your usual words and deeds are the accumulation of colleagues' comments and opinions, so it is a good thing to have problems and correct them. If there are problems in business, you should be familiar with the business and do your job well. If emotional intelligence is not enough, you should practice speaking more and your communication skills more. People who meet friends will say a few words to make everyone happy. People who don't do good deeds will make everyone hate, so you should exercise yourself. Find books, find tutorials and practice step by step.
