A form of therapy I suggest for this is EMDR, it’s specialized in helping with trauma. Even though the trauma you have is rather intense, it’s still worth a try. Basically, you start off by doing building blocks, basically, you begin to think about the negative beliefs you have about your trauma, my negative belief for my trauma was ‘I should’ve done something’, definitely fun- the next stage is when you begin to work on imagining your safe place, mine is a cozy bedrooms with cats. And, as this ends, you will begin to get into the memory of the trauma, and you’ll keep going until you feel nothing about the memory and it’s more like a sad memory but hey, you can move on. Once that ends, you will replace the negative belief with a positive one.
