Some things I have noticed over the years dealing with all this trauma, was when i first crashed back in 2009 after to much backpacking and Karate training, I suffered from CFS. I was sleeping more than I was awake, I had all the symptoms you mentioned Beth above, and over a period of 18 months, with no special diet, no supplements, hells I was still smoking shed loads back then and doing the occasional recreational drugs, I recovered and went back to a normal life.
It was only when I went back to work full time and experiences lots of stress, did I start my slippery slope into AF, and being locked in stress mode. Over the next three years thast become what we know as 3C/3D AF, completely HPA dysfunction. There is a massive difference between AF and Chronic-Fatigue-Syndrome for me, if I could go back to the Chronic-Fatigue-Syndrome days I would be more than happy!
