I have also read some interesting things about Autoimmune illness and personality types. The research was a combination of work done in Denmark, the UK and New Zealand. It showed that abuse when a child caused behaviors in adults that resulted in autoimmune illness. The report was credible and matched my behaviors very closely. I wasn't abused, the exact opposite. But, I had been very ill as a child and what I experienced then is I believe the reason for me now. I was taken from my home by three strangers, (EMTs) put in a big cold van (ambulance), taken to a large drafty noisy building (hospital), and put in a room by myself (ICU). I was not allowed food or water (because that would have killed me). I spent three months in that hospital and although I know my parents visited very often, I don't remember one of those visits. No one told me what was happening or why I was there. I guess they thought a 3 year old wouldn't understand.
