I've had panic attacks a few times in my life and the last one was basically my brain trying to torture me. I felt like I was on the brink of having a heart attack, then I felt like I couldn't breath, then I felt like I had a severe burn all over my body, then I got hit with terrible nausea. Over and over for the span of just over a week my body just tormented me. 3 ER visits, multiple trips to the doctor, thousands upon thousands burned in medical bills, and I was just told over and over that I was perfectly healthy. Eventually I was prescribed Sertraline (Zoloft) and my torment ceased almost immediately.
That week was complete hell and I do not wish it upon anyone. Anxiety attacks can be dangerous if untreated. Stress needs to be relieved. I was too much into my work and was trying to balance way too much in my life.
