My anxiety has been way better lately, but one thing I've noticed is that when my gerd acts up then my anxiety does. I have not been able to sleep because I've been feeling like I'm not breathing right. I take my oxygen and pulse. My oxygen is 98 and my pulse is 65.. I don't get this. I guess it's from the discomfort of acid reflux, but my mind will start thinking of multiple scenarios and that makes me feel like it is something more serious.
