Hi smin, it sounds really frustrating that she's focusing on the wrong thing at the moment. Your trauma is definitely important, as you said. Although in my experience therapists don't seem to want to start with the biggest things first. A big part of therapy is the connection between you and the therapist, so she may be just trying to get to know you to help as much as she can. Asking questions about childhood is a good way for them to do this.
