Hi, I was looking for information on the symptoms i'm having. I was reading your panel from back in 2006. I didn't know so many people were expericing the same thing as I. I have diaherra, vomiting, chills, shaking, and I faint. I feel so weak and drained when the episode comes. Sometime I feel like fainting and I don't, but most times I alway faint. I went into cardic arrest during one of my episodes. The doctors can't figure out any thing. They say it's stress also, but i wasn't feeling stressed when these episodes come on. I have panic attacks and they keep asking me if I wasn't having a panic attack? I know how my panic attack feel and it's nothing like this. I just need advice and help. I feel so bad most of the time and it's affecting my life and career. Could it really be all from anxiety?
