Why are you always depressed in the workplace?

Boss, I've had enough this time. I know this is not what I want. I will finish my work and then severely fire my boss. The coolest thing is that I've been dormant for half a year and I'm really getting better. I am very happy to quit my job and go to the postgraduate entrance examination. After graduate school, I'm going to the superior department of this department. Of course, I like this job very much, but I don't like the atmosphere there very much, which doesn't affect that I like my job. I also hope you stick to it and see if it is the life you want.
