I think this is very likely the reason OP feels the way they do. I just left a job after 2-1/2 years. I knew I didn’t want to stay there from the moment I started. It was an in-beteeen job while I looked for something better. I knew it, my bosses knew it. I was so excited about the prospect of finding a new job and actually doing something better with my life. However, the moment I actually got a job offer, that excitement turned to anxiety and dread. I was venturing into the unknown. My mind instantly shifted to focus on all the negatives of the new job.
Change is terrifying. So much so that sometimes we simply try to do nothing in order to avoid it.
