I was just outside at the park with my sister when all of the sudden these anxious feeling started. I was having racing thoughts mostly about suddenly dropping dead. A huge fear of mine. So now I am dizzy, I have extreme detachment from my own body almost as though I cannot feel as I normaly do and this sense of impending doom, I am so nauseous and hot all over my stomach is in a knot and these thoughts are coming with wave after wave of "panic" I'm really scared I am about to drop dead. I have no chest pain at all and my heart is not racing usually I don't ever have the heart racing or pain I just am so scared and don't fell right I am so afraid. Does anyone else's attacks go like what I have just described? Biggest issue is the detachment it is like im not really here in my own body I can't feel it, and the racing thoughts, catastrophic thoughts and sense of impending doom. Please anyone?
