P, you are a unique case, I grant you that. You're especially unique here as most people here got PTSD from abuse of some kind. Just an anomaly of this board, I think. But so it goes.
The good news is that I think you answered your own question. Stories are everywhere about people surviving disasters, plane crashes, and accidents of every kind and size being stricken with PTSD and ultimately achieving a nearly completely normal life. It happens. The chances of you achieving this seem good since you openly acknowledge that you will never be "cured".
I'm sorry there aren't more stories like that here but I'd say hold on to that hope and determination, it'll probably serve you well. And try to have realistic expectations as you progress.
