Last to first:
I know... funny how things change, isn't it? I'm somewhat reassured at the thought that we're always changing, often in response to environment or crisis. I've been through multiple crises the last six years, and these days feel like a bit of glass formed in the inferno, half covered in ash and still hot to the touch for the unwary who attempts it.
Something discussed in my stress, trauma and PTSD class (taught by a Navy Iraq war vet clinical psychologist) that "trauma shatters belief." I think that's true for many. Not just religious belief, although it often manifests that way. Shattered belief in anything that one once held as true, secure, unchanging, unquestioned... and in recovery one has to find a way back, although it might be to a place that doesn't look the same.
