Welcome to PC ! I read your introduction and was really thrilled that you started working !! Many many times when we are anxious, we tend to hold our breath, therefore, we feel that we are having trouble getting a deep breath, or that we cannot catch our breath. Try diaphragmatic breathing, inhale thru the nose, out thru the mouth, making sure your BELLY moves more than your chest. That means that your lungs are filling to the bottom. IF you try it - and see that your chest rises more than your belly - or that your shoulders move up and down, you might want to practice while laying down to start with.......as you might get a bit dizzy if you are not used to getting appropriate oxygen exchange. And that is a definte YES to people suffering from anxiety feeling the way you describe !
