you need to check your adrenals with a 4-point cortisol saliva test,anxiety is caused by weak adrenals and hypoglycemia is weak adrenals also,you can have hypoglycemia but still NOT show up in blood sugar tests,my brother is living this now,try to get a 3-4 days of saliva-testing 4 times a day done...frequent-does-chelation.yahoo.com
nonsense, anxiety is caused by a lot of things, in Disturbia's case I think it's likely due to misinterpretation of normal stressors, or a hypervigilance/hypersensitivity to these normal stressors. Have you considered cognitive behavioral therapy? Re-appraisal of sensory information coupled with a improving your grip on the resulting cognitive processes: basically preventing your thoughts from spiralling into an anxiety attack.
I would seriously step away from self-administering test. With your history of depression and anxiety, your neuro-transmitters are likely out of balance. Test may be a temporary fix, but may do more harm then good.
