I have a history of depression and anxiety. I was placed in an extremely tense situation at work yesterday and lost my cool. I hyperventilated and was trying to hold back tears (didn't happen) I also had a lot of trouble breathing. Short shallow breaths were all I could manage. Late last night and this morning I have severe pain when I take deep breaths. And my left lower rib cage around to my back hurts. Also what feels like under my left collar bone to up the side of my neck. Is this strain from crying? Or what else could it be?
