Buttercup, as the others have said, please get checked out by your doctor, or at ER as soon as you can. Breathing issues are not to be taken lightly. It could be a reaction to a medication, or inflammation in your lungs, or so many other things...none of them good.
Better safe than sorry, and please...if the doctors can't find a reason, and simply chalk it up to stress or anxiety, don't worry about it. Stress can manifest itself in many many ways...the main thing is to make sure you're alright
So...off you go please, and report back when you're home so WE can stop holding our breath!
