In my experience, talk therapy alone does not work for trauma. People often wonder why things aren't getting better after going to therapy for years. The reason is although you may have been sharing your whole life story in a safe, trusting space with a therapist, complete healing cannot occur. With that said, having a therapist you are bonded with, in of itself is beneficial.
I use a holistic person-centered approach to trauma. I believe at our core, we have an ability to heal. I facilitate therapy, but it is the client who innately heals themselves. I work by looking at the interaction of thought patterns, beliefs, emotions, and the body. Additionally, I implement Mindfulness, a practice of being present in the moment without judgment.
EMDR (Eye Movement Desensitization and Reprocessing) is an evidence based approach in the treatment of trauma. I am currently in EMDR training and can use it in counseling. EMDR has also been successful for the treatment of depression, anxiety, and many other issues. It is an integrated protocol fostering healing of the mind and body.
