The only thing I can suggest Dulciana is when you bend to ‘fill your lungs up'
as it were, is hold onto to that breath for a few seconds, then release it slowly
through your mouth. That's what I do, do that a few times, until it's calmed down.
Try NOT to panic, this makes it worse. Then when your over ‘the episode ‘
try some 4.7.8 breathing.
And when it's settled down, distraction works.....gets your mind off it..
Really hope this works for you, and is helpful....take care.
