My veins sink in and my heartbeat becomes faint. My hands start sweating and I begin to get panicky. Which only makes it worse. My heart skips more than usual as well. I have been to the lexington er for this but they just told me I was fine. I know my body and I am not fine. Please help me before something terrible comes from this. It is haunting my life and honestly, I just don't feel ok. I have smoked cigarettes for 8 years now. Please don't blame this all on cigarettes...though I don't doubt that smoking may have something to do with it.
