anxiety is a chemical imbalance so I take a beta blocker and a anti depressant. Thats why all of a sudden you get the physical symptoms our brain gives our body the wrong message,I suffer from anxiety because I started perimenopause and my raging hormones threw everything out of whack so I eat better stay away from triggers that I'm learning about, yoga and lots of vitamins and living the good life...I quit smoking . no alcohol...listen to my ocean c.d at night keeps my mind from thinking. They say this ic highly cureable but we have to help ourselves and that is so hard for me the discipline that I have to have to live this way takes work but I think...wait I know it will work in time. I am 42 years old and my habits will not change overnight. Good luck
