What kind of mood is it to resign?

After working in the original work unit for one year, I went to a new job because of the introduction of my relatives. Because I had my own wishes and some family relationships when I left my job, I didn't adapt to the new job after I got to my new job, so I resigned after working for one month. But since I resigned, I feel that the whole person has no motivation to work. Although some units have been interviewing for jobs, I always feel that I didn't go to work.
