Just finished Pete Walker's book, also recommend. One of the most helpful things I've come across for dealing with the neglect I and my siblings experienced growing up. It's hard to know what you don't know... until you know it!
Really glad you liked Pete's book. Janina Fisher's "Healing the Fragmented Selves of Trauma Survivors" is my other greatest of all time book in the area that I recommend. It's my first go-to over "The Body Keeps the Score" just because somehow Dr. Fisher has a method that works palatably with someone from even "low-grade" trauma to even what I think would be some polyfragmented DID systems, in some kind of Jedi-mind trick set of tools that works really well while dodging most of the myriad of situational triggers that are unique to each trauma survivor. I highly recommend it if you're interested, it adds a flip side of compassion and self-team building that I think Walker's book can go a bit harshly on as it seems to be more centric on the part of the brain experiencing daily life as the reference for others to be compared to. Both books are fantastic and balance each other out, I just started my second read on Fisher's book and am trying to wrap up Walker's. Give that one a go if you're interested, the audiobook is the cheapest!
Happy to chat about the topic, I love and am passionate about this field as you can guess. :D :)
