@kjconrad I know the question was directed to Tonya, but wanted to chime in; when I did the exact same thing when I first came down with the SOB, it took a couple of days of fighting the urge to take a deep breath for it to go away completely and for my breathing to "reset." I only breathed through my nose and when I couldn't resist any longer, I took a deep breath only through my nose and breathed shallowly throughout the day. I also did many breath holds throughout the day to build up CO2, which also helped.
