Some of the things I learned in this forum are writing it out, starting each session immediately with the hardest topic and asking my therapist for help getting it out. I send an e-mail the night before my session (or earlier if something big comes up). In the email, I blurt out what is most pressing for me and ask her to please bring it up in session and help me stick with it until I get the words out. When eye contact feels too hard, I cover my face, close my eyes or look at something else in the room. Starting with the hardest thing gives me enough time to regroup before the end. Once I experienced how gentle and caring my therapist responded to my most shameful memories, it started to get easier to share. One time her response missed the mark, and I didn’t realize it until the next day. I’m a slow processor! We talked on the phone and repaired and reconnected and things got even better. Trauma therapists really are experts at this!
I frequently ask my therapist to remind me I can do it. We say out loud together that I will not die from telling secrets or feeling emotions. I realize it sounds ridiculous, but there is a part of me still feeling terrified of the risk.
You can start with smaller, less painful memories and build trust slowly...or consider ripping the scab off and starting with the worst. You deserve the experience of loving, empathic witness. It changes everything...
