Hi,
You sort of asked two different questions, really. You asked about it being cured, and no, it's not what one could call curable. You also aksed when the nightmare goes away, and I think that's different. If it's been 10 years for you I'm sure you're more than tired of dealing with this thing, but truly, with the right therpy, perhaps getting the chemistry back to where it should be and just plain time the nightmare part can go away. Validation helps a ton, which is one of the reasons this forum 'works'. I think an awful lot of us ignored the whole thing for so long, didn't speak of either the trauma or the PTSD for various reasons that it did get worse.
The healing can happen, as well having what anyone could happily call a nice sort of life. There's back-slides, manifestations which remain intrusive as hell, some asects which are just a pain in the *ss, in everyday living, but the nightmare really does go away.
I hope it gives you some optimism and hope to tool around some of the articles and threads here, and see that it's going to be ok at some point.
Take care, and peace,
Anni
