I think you should keep talking about it. I'm sorry that you experienced a trauma -- and although I understand it's difficult, I believe that it's what therapy is for. To keep talking about it, keep pushing through the pain. If anything, take a breather or two, have your therapist calm you down and help you settle when it gets to be too much. Write some of it down and save it for next session. It'll be painful to talk about, regardless of how many times you've talked about it, but the goal is that it hurts differently; hopefully less, the more you do.
It's like nightmares. Nightmares are scary, but they are needed -- they help us process our left-over fear and anxiety and once we wake up, we're cooled off from the horror of our nightmare. Sometimes we may need to process, but all of what you're doing in therapy and all of what our brain does is consistently try and process and protect itself. Hang in there. :hug: You're doing a really good thing and I hope that this break has given you some insight.
