Hi, one of my anxiety symptoms, at least I think it is just caused by anxiety, is constantly sighing or taking a deep breath. I have done this 5 times or more in a minute sometimes when I am really bad and too many times to count in an hour. I feel like I have to do this to breathe or to relieve air pressure in my chest or lungs. Sometimes I'll yawn at the same time or a yawn will turn into a sigh. It is making me tired and hurting my chest breathing in so deeply so often. I did try breathing in through my nose, holding my breath, then exhaling through my mouth many times to do what i read some have suggested: balance out the CO2 in my lungs. But that hasn't worked. I just sighed 4 times in the two minutes it took to write this. They are getting further apart as I relax, but they are still a nuisance. It feels like I do it automatically now. It is worse when I walk or do any physical activity. Anyone else get this? Get constant, uncontrollable sighing or deep breath taking? And what do you do about it? Though I am not breathing fast, I feel like I am hyperventilating. What do I do? Thank you.
