without taking a breath.?
I am not a smoker. I am not sick, overrweight or anything. I have been stressed. Can it be something else?

It could be stress. Do you feel extremely tired and dizzy also? I went thru the same thing, and come to find out I had a bleeding ulcer and was extremely anemic, and ended up in the hospital. Please don't ignore this - go to the dr and have it checked out.

Your breathing problem could be caused by many different things. Many diseases and illnesses present themselves differently for each patient. It could be anxiety, depression, allergies, or something else environmental. It could also be something more hazardous and need attention right now. If you can't breath this is a major problem, obviously. Please go see a doctor and good luck.

Well, I don't think it's anything else except sleep. You can be really sleepy.
