I got panic attacks for a while a couple of years ago and I know how terrifying they can be. Do you have coping strategies? My counselor told me to try to concentrate on breathing very slow and deep, and also to do something that would comfort me. For me it was to wrap my arms around myself really tight… Also, rubbing my hands together would sometimes help. None of it was foolproof, but sometimes it was just enough to distract my brain.
Frankly, I don’t know how you get half the things done in a day that you do. It’s a big deal. Go easy on yourself.
