I was going to respond yes and describe my experiences of PTSD, but I just read the faith in society thread and realised that the OPs are the same. So I want to note that PTSD from trauma in the medical system is certainly a thing (like any other trauma) and it can be quite terrible - I have witnessed it in my mother and I experienced short-term trauma in it myself - that you would question society after is not shocking, because of the function that the healthcare system serves in it. I am sorry for what you went through, can'tdecide. I would definitely consider that it could be PTSD and that might be a medical explanation of your symptoms.
I don't know what happened to you, so I will just mention that my mother experienced shocking effects from withdrawal from a particular medication. The company was sued actually because many people felt they were misled about the dangers of withdrawal syndrome from this drug. And my mother's doctor did not warn her at all nor did they take her seriously when she reported her symptoms (of course she wasn't told to report back). So she suffered in very bizarre and painful ways and was told that they were symptoms of insanity. The invalidation messed with her perceptions of reality and sense of self, and the effects themselves were quite an ordeal. The weird neurological symptoms and the gaslighting both created profound shocks that traumatised her and prevented her from being able to move on in a typical manner.
Some of my acute PTSD symptoms are gone with years and years of therapy, but I'm still hypervigilant and have a lot of long-term emotional problems. The nightmares, the reliving, the dissociation did ease with therapy over time though. I vented my anger and resentment quite a lot over the years. I would say I used to think about my rapist every hour, now I still think about him every day, but often it's dispassionately. To be fair, I was mentally ill before these traumatic lifechanging experiences. Also, the isolation I experienced after it happened has left a deep emptiness in me. And I'm still very hypervigilant (startle reflex). At least the sleep disturbances stopped
