I think that I can relate to this problem from when I was a teenager. There were times when I would feel an intense sense of nerves but I have no idea as to what was the cause. PANIC couldn't better describe what I was going through at the time and I was really worried for myself but I don't know why. I can remeber thinking that my days were numbered and that death was just around the corner, but here I am 10 years down the line and feeling fine. I would be very interested to speak to people with this problem. please feel free to email me at markerburns2@hotmail.com.
look forward to hearing from you
