The anxiety about this thing is overwhelming. Been going through the same thing myself for six months. Believe me the D causes the anxiety first. I never knew what anxiety WAS until I had this. When that D comes I feel so out of control, scared to death, weak, shaky and depressed. I think part of it is a chemical imbalance when it happens. It's so violant and traumatic to your body it sort of sends it into a tailspin I guess. I'm still not concinced that I don't have something seriously wrong with me.
