I have the same anxiety symptoms as you! It's real! Even when I'm not "worried" about anything, I can have full blown panic attacks. Shivering, hyperventilating, feeling of impending doom... It's the worst feeling ever. I found taking [wiki2="Magnesium"]Magnesium[/wiki2] supplements daily help more than anything else I've tried. I also take daily turmeric, and with [wiki2="Probiotics"]probiotics[/wiki2], those 3 supplements keep me in remission and anxiety free.
