I have wondered this for a few years. But never thought to post it here. When I am feeling very sad and depressed I breathe oddly. Its like I inhale through my nose in little breaths. Maybe 6 little sniffs in at the same time. Over and over again. Its sort of involuntary. I was curious if anyone else does the same thing. I asked my homeopathic pdoc about it. But she just looked back rather blankly. So I am asking the experts here, lol. :hug: for anyone wanting one.
