ryan, it's interesting you mentioned ptsd. I think I have had a few key incidences in my past that i've never delt with properly, and these are rattling around up stairs causing havoc. I wonder if not grieving properly after a parents death when I was young would have anything to do with it? Though mine seems to have more of an anxiety element to it. And Jeremy feel free to highjack, the more the merrier.
Glad I live down the road from a nurses training hospital!
