What causes me to suddenly want to take a deep breath and can't and then i feel sob afterabit lightheaded and a lil chest pain then it all disappears?

Difficult to answer: Your symptoms do not point to a particular problem. Suggest to see your doctor for thorough evaluation. There might be an element of anxiety as well.

Event recorder: Some cardiac arrythmias can cause similar symptoms. A transient supraventricular tachycardia with accelerated ventricular response can sometimes cause symptoms like that. You will need an event recorder device so that next time you experience those symptoms your cardiologist can determine what was your heart rythm at the time. Then evidence based treatment can be done.
