Thanks for suggesting the book, I've started reading it and honestly feels like this will help as it's actually talking about the nervous shock which I've been telling my Doctors since June!!
It all Started when I took a cold shower immediately after intense workout. When I came out, suddenly I felt like I'm not able to breathe. My sweating stopped abruptly (usually I sweat for sometime even after shower) and I turned pale. I did not faint but was not able to breathe properly for many hours after it. Never felt normal after that moment.
It was not a scary incident but I think my brain/body overreacted.
Appointment with Psychiatrist is on Saturday.
