Breathing difficulty in anxiety !!!1?

It would depend. I went through this for a few months and finally got to my lowest point of agrophobia (constantly had to stay home, in my room or I would hypervenitlate) If you make sure you dont let yourself resort to that then things should let up as soon as you learn there is nothing else wrong with you and that you will NOT die from anxiety or panic attacks. I have this now where it comes once every 2-4 weeks (used to have it 24/7 a few months ago). Just make sure that you do NOT give in to your body's reaction of freaking out over nothing. Have you been through stress or loss lately? What kind of meds? I have Ativan but only use it when I absolutely HAVE to.
