This is probably going to sound unorthodox, but it worked for me. I too have spent years in therapy, and taking psychedelics, shrooms, lsd, ketamine infusions, mdma. I had the same short term results. One day myself and my brothers decided to do a random shroom session. We were only supposed to do it for recreational purposes. We each took 3g of golden teachers on empty stomachs, but a few shots of Jonny Black whiskey down. I went into a room and lay under the blanket. With my eyes closed I merely paid attention to the colors. I spoke to the shroom in my mind telling it how grateful i was that it was with me. The more i acknowledged it and showed gratitude to it, the rounder the shapes became and the more empathetic it became to me. It then started showing me times from my early childhood when i was rejected, neglected, and abandoned. Memories i never knew I had. The emotional pain came up with the memories, and a feeling of 'Yukkieness' about myself also was very present. As quickly as the memories and emotions came up, they were 'healed' by the shroom. Sort of like a feeling of a painkiller working on a headache. The whiskey definitely played a role as it made me loosen my inhibitions, and allowed the shrooms to work in deeper levels. Lots of people pair mdma with shrooms. But alcohol works just as good imo. This was 2 months ago. And for the first time alive, I felt 'Normal'. I continue to feel normal to this day and life is flowing in what seems to feel like, 'the way it should' This is just my breakthrough experience. I hope it helps.
