I personally found great success with EMDR. It’s used to help people with PTSD process deeply repressed emotions or traumatic experiences and it brings them right to the surface for examination. It’s one of the few ways I can freely access all my emotions and feel safe. I’ve laughed and sobbed bitterly, screamed, found peace. It might be useful for you. My husband also did it (he doesn’t have PTSD) and I can honestly say he found it life changing. He was extremely repressed, to the point where he was compartmentalising parts of his life and very passive aggressive and unable to say what wanted. After 3 sessions of EMDR it was like the world had been lifted off his shoulders and he expressed himself so much more freely. He recommends it to everyone now.
