Is air hunger caused by stress or anxiety?

It feels like I cant inhale or exhale normal. Shortness of breath. I need to inhale deep but feels like I cant get enough of air. Is this anxiety or stress? Or is it a w/d sx? I dont feel any anxiety symptoms. Only this. It is really scary.  I keep thinking about this all the time like intrusive ocd thoughts...

I had it with just anxiety even before benzos. Anytime I got really anxious or nervous I had it. It’s a anxiety symptom, but stress causes anxiety, so I guess it’s both.

I've had this, it is probably one of the strange symptoms. It is strange but it went away with benztropine administration

Withdrawal for sure.

It eventually went away for me.

I can't even remember when. One day I just realized I could breathe normally again

It will pass in time.
