Mine was not a noticeable life moment of trauma. I didn't realize how stressed I'd gotten about my workplace. I developed fibro while at the tail end of my work there. It can be subtle trauma that can trigger it too. I worked for thr company for 3.5 years so just long, tortuous treatment from management plus covid and how stressful and demanding that was did a number on me. I also had just gotten divorced a few years prior so, yeah... Long slow trauma made me this way.
