I think seeking out things concerning the trauma is natural, I would read books about people who had been through the same experience as I have. It was the only type of books I read over an year after it happened. For me it helped to understand what I was going through and I don’t think it’s a negative thing as long as you eventually stop. I also have control issues and for me it was a form of feeling like I was in control. Not sure why, but it helped.
