Hello nickyhy,
well, from what you are writing you seem to be suffering from some sort of depression.
You are right that grief can cause us to be depressed. What happens from a biological point of view is that grief or any trauma for that matter can cause the body to produce stress hormones, such as adrenaline and cortisol, that interfere with the synthesis of serotonin, our feel good hormone.
Most people recover after say six months of time, and start producing serotonin again.
But for some people depression does not seem to disappear and depression continues to rear its ugly head, and especially when this is related to the memory of the past trauma. (your nanny). This would be classed as post traumatic stress disorder (ptsd).
See:
“post traumatic stress disorder(ptsd and hypoglycemia” at our web site
the reason is that the body continues to produce excess stress hormones, especially adrenaline, without any external cause of danger or stress. The fact that you may have changed jobs might have triggered a stress reaction again, and we need to find out why you are overproducing stress hormones.
The most likely reason is that you may have an unstable blood sugar levels. Adrenaline functions to raise blood sugar levels, when they are low, as in hypoglycemia. You said that your nanny was diabetic, and thus I gather that you may have a diabetic gene in the family. The prediabetic condition is marked by unstable blood sugar levels causing emotional upsets. This can be treated by going on a hypoglycemic diet (similar to a diabetic diet).
You can test yourself with a paper-and-pencil test called the nbi at our web site for hypoglycemia. You can also be tested with a special glucose tolerance test for hypoglycemia (gtth) and this is described at our web site.
Please familiarize yourself with the connection between emotional upsets and hypoglycemia and once you understand the underlying mechanism, you may be able to solve your problems by a change in diet.
Please discuss with a therapist.
