I have generalized anxiety that is usually well controlled, but lately I've been having panic feelings all of a sudden. It first started a couple of weeks ago when I had a respiratory infection with asthmatic bronchitis which was triggering anxiety attacks due to inability to breath deeply. Now, the panic feelings seem to be happening intensely a few times a day even though my bronchitis is better. Does anyone have any ideas of preventing these attacks and also how to recover sooner when after they occur?
