Where to go from here

The other day I found my police report that I made when I was 15 years old. I don't know what possessed me but I chose to read it. I recently started therapy after 20 years because something triggered me took me all the way back. But my memory has been not at so clear and when my therapist Ask me about some details they are a little bit blurry. So this report brings the stories back to the surface more clearly. But now I don't know what to do. I feel really detached from them and I don't even know why I have them still. Therapist thinks it's good that I found them I don't know what to do with them. I know that all the stories are true in my statement but it's almost like reading somebody else's story. And now some things starting to come out that I didn't know where there either. I'm so confused
