Those days when I was a "Project Manager"

The Project Manager resigned and I took over from him as the project owner, responsible for the development of the project. I have always hoped to be reused. This time I finally got my wish, after I took over the project, other colleagues gradually became owners of other projects and were doing the same thing, departments and even the entire company do not pay much attention to this project. Projects under the responsibility of other project owners are more important than mine. When I took over the project, the Technical Director talked to me. Now, let me select one from Project A and Project B, at that time, I took over the challenge of Project A, so that YY became the owner of another project. Now I think that YY was responsible for project a and he was responsible for Project B, I don't want to kill my uncle Ren, But I died because of me. I accidentally made a "Revenge" with yy. There are many things that need to be coordinated by YY in the project I am in charge, in the process of YY's cooperation, he tried his best to present himself and pushed me to a zombie project owner. He blamed him for not understanding the world, and thought about the research technology he had been working hard for many years, YY is indeed better at communicating and coordinating with various departments... as the project draws to a close, my employees are also slowly drawn from other projects. I have only one job left to test with colleagues from other departments, this makes it difficult for me to move to a "test" role. In name, my responsibilities are very important. In combination with other departments to test project problems, I want to arrange for my colleagues who have been transferred to make changes in time. I still The project owner. With the passage of time, the transferred colleagues quickly invested in new work. With the business needs, their work is getting heavier and heavier, the Technical Director talked to me and said, "They are all busy. You can modify the problems later!" In this way, I became the person in charge of all the questions for project development and testing. I started to get familiar with what everyone wrote. Code To analyze the problem, I am still the project owner. I have no Comrades around, and I am fighting alone...
After the project was over, I was transferred back to the department because there was nothing to help me with the project I was scheduled to be in charge of YY. On the first day of work, the technical director came to me, let me help you solve problems encountered in the Project of YY. I thought the problem could not be solved, and I passed with great enthusiasm. As a result, YY's subordinates asked me to help him find the code on the page. At that time, I was so angry that I almost never fainted, ask myself, I am no worse than anyone else. I want to say that you don't know my strength yet, the new younger brother. How can I say that I used to be the owner of the XXX project, you asked me to do this. I comforted myself when I was working for the people, but I had to spend all night without knowing what the old man was thinking about as a technical director, why can't we make good use of it. The next day, YY came to me and said that he was going to test the order and asked me to place an order for him. Dizzy was so technical. You tested it and asked me to place an order for you, Mom. There's no way to place an order. Who wants me to be under his door now...
Maybe I should talk to the technical director so that he can arrange my work properly... maybe there is nothing at all, but I am in the intestines, and it will not take long for me to be reused again, but now my heart is really uncomfortable...
