First, I had heard of the author's online presence before (which I found disturbing) but I did not make this association before research - which I did halfway through reading,,, 
I dnf'ed at 70%, and then skimmed to the end, out of curiosity.
It is clear that the author comes from a severely abusive background, emotionally and physically, both at home and in school. A lot of it stems from being "different" (the author currently identifies as non-binary). He recounts his really severe dissociative episodes in response to the abuse, as well as the other mental repercussions of it.
The writing and structure need work. But my main gripe with the work was the telling. It is fine that, in a childhood memoir, the memories are vague! Having such clear memories and dialogue brought me out of the tale - it just cannot be completely accurate. If you do not establish yourself as a reliable narrator on your memoir, it is hard for people to keep reading.
