I have the same thing and it’s driving me crazy! Someone on here said it well...it’s like having to manually breath rather than it being involuntary. I like the “air hungry” description as well. And I almost feel like it’s an addiction to the deep breath. I’ve felt it my whole life but it has been horrible for a little over a year. I’ve found a few other similar threads and it seems overwhelmingly that we are healthy individuals who don’t relate to the excess anxiety claim. I’ve tried the breathing techniques mentioned along with being a meditator and nothing seems to help. I’ve even tried anti-anxiety meds. It feels very physiological. I hope to stay in too with this and other threads so that maybe one of us finds the solution.
