Well it all starts off with a bit of nervousness. Soon your heart starts to race; it goes up then down then up then down -- very sporatically. You begin to become frantic, disorganized, and me -- I really feel I am going crazy and am about to die. Sometimes I feel terror that is almost paralyzing.
While all this is happening, I become dizzy, and lightheaded.
The thing that makes it the worst though, is there is no external cause. Like its not like there is a murderer in my house, it is terrible because it comes from the inside.
