Has anyone ever had a panic attack that they swore was a heart attack??? I had chest pain last night, felt like I couldn't breathe, hard to swallow, terror, rapid heart rate, both hanRAB were nurab, felt totally out of control, scared, face and lips felt strange. The more I thought about it the worse it became. The chest pain was not horrible. I tried to calm down by breathing deeply, but the more I thought about it, the more I focused on the symptoms. I did not want to talk to anyone. So, I took a xanax, and did deep breathing, and must have finally fallen asleep. I am so scared to have this happen to me again, I truly thought I was having a heart attack. I use to have panic attacks a couple years ago, and I have not had one like this in years. How do I know for sure it was not a heart attack??? I am totally freaking out still, and so scared to feel like this again....Please someone tell me that they understand what I am going through. Could I have slept through a heart attack??? Thanks!
