@mostafamahjoori let me know if the anxiety medicine helps. Have you looked into breathing exercises? Not only can they help with the SOB/air hunger, but also with dealing with nervousness and anxiety. There are methods where everytime you feel anxious, you breathe slowly in, hold your breath for a few seconds, and slowly exhale to slow down your breathing and reduce the flight or fight response. It would be worth having an exercise like that ready for any of those times.

How is your diet? You mentioned bloating, so I'm wondering if there's a digestive issue, or maybe certain foods that might be causing this.
