"Chronic Fatigue Syndrome and Fibromyalgia are triggered by the Hypothalamus overworking the Pituitary and Adrenal Glands, This is why Reverse Therapists refer to these conditions as 'HPA Disorder' referring to the Hypothalamus-Pituitary-Adrenal axis.

The reason the Hypothalamus does this is based on a conflict between Bodymind (working mostly through the Emotional Brain, or Limbic system) and Headmind (working through the thinking centres in the Frontal cortex). Bodymind notices that the person is emotionally vulnerable in some way and sends emotions of various kinds to signal that action is required. This could involve taking more time out for oneself, saying 'No' to unreasonable demands, speaking up about personal needs, or doing more things to boost enjoyment and confidence.

But when Headmind interferes with this natural cycle by coming up with worries, predictions of disaster, or thinking that attention to emotional needs is 'bad' or 'selfish' then the person becomes trapped. Bodymind notices that the person is in danger of emotional overload and so it uses the Hypothalamus to switch on an alarm response that produces the symptoms. "
