For the past month, I've been having this unexplained condition that triggers almost every day in the night time. I get this sensation that I almost cannot breathe, and when I do, a feel a weird painful sensation towards the inside of my throat, and my heart pounds very hard and slowly for about 2 beats (I also feel this in my throat). During this, I sweat a lot and I tend to feel dizziness and some nausea. This also causes me to feel very fearful. Also when I take deep breaths, I have to yawn which makes me feel like those deep breathes didn't calm me down. My heart also beats very fast (about 120 BPM) while this happens. I am 14 years and overweight. Anyone with a response?
