Well, I found a new trigger for my PTSD. See, for the last while I have been reading "The Dark Tower" by Steven King, and partway through the second book, I started getting shaky. But I didn't connect it to what I was reading, because it didn't contain my usual triggers.

But partway through the third book, I finally realized why I was so triggered - three of the characters suffer from a split in the mind. The first one is literally a split personality, with the two halves unaware of each other, and the other two have been caught in a kind of time paradox, and cannot reconcile two different memories of events.

Once I realized I was being triggered, I had a choice to make, and I chose to keep reading, hoping for things to improve, and that's what has happened - the lady with the split personality has been made whole, and there is (at the point I am at in the story) now hope for the other two characters as well.

I'm glad my choice worked out, but I am going to have to watch out for this kind of thing in future stories I read ...
