So u should have adquate sleep , have little less food not full stomach , plenty of water. Do , excercise , yoga and Pranayama wl help u in breathing , do breathing excercise too

Your need to take a deep breath or yawn could be due to stress and anxiety.  People who are anxious feel like that. I strongly suggest you to consult a Homeopathic physician.

There isn't sufficient information to reach a specific diagnosis. I would advise you to visit the ER and get evaluated and undergo the necessary investigations to find the underlying cause of the problem and have it treated accordingly.
