Feels like i will 100% STOP breathing with dizziness

Hi all,

For some background I am a 21 year old male. I have always had symptoms like skipped beats and shortness of breathe but recently it has gotten much worse. Randomly throughout the day it will feel like I am about to stop breathing and will pass out because I get so dizzy. It doesn't feel like air hunger, but literally feels like my breathing will completely stop. Now I always feel pressure in my chest and left arm. I have already been to the ER 4 times and have seen 3 cardiologists and an electrophysiologist. I have gotten EKGs, Ultrasounds, X-rays, Blood work, and even a 30-day monitor and they tell me they cant find anything. Can anxiety really make you feel like you will just stop breathing like this? I get so scared because it also seems like I start blacking out. 

Yes, Anxiety CAN do this. You have to realise that the brain is an immensly powerful muscle and has control 9n practically everything we do.

The fact that you have seen a Cardiologist and I suspect they havr done all tests would or should give you comfort in knowing its unlikely to br serious.

Get a d-dimer blood test, you could have a pulmonary embolism or multiple pulmonary emboli. They don’t show up in X-rays and they can mess your heart rhythm up. If your D-dimer comes back high get a chest CT with contrast.
