Hey, stumbled upon your posts here while looking up more things about MDMA therapy on google. I had read your stuff previously on reddit and it was helpful. This is what I currently doing from these articles (links below). To me it seems I need to feel the anger somatically and let it pass out and through the system because it was blocked as a child for me as it was unsafe to express it. I don't see how anything short of letting ourselves feel the anger won't leave us with energy being wasted pushing it back down which could instead be used instead to other more valuable things.
