Re: Shaky and jittery?
I'll also add that stress and anxiety can be directly related to low blood gucose levels. When your blood glucose drops too low your adrenal glands release cortisol, a hormone that naturally raises the blood glucose levels without food. But cortisol is also the "stress hormone" - it can cause an adrenaline rush, the fight or flight syndrome, or just general feelings of anxiety, depression, etc...
I suspect that if it does turn out that your blood glucose has been low, that once you get it under control much of your stress and anxiety will level off as well.
