This morning I had a meeting to attend (I'm a teacher and it was a meeting regarding a student) and during the meeting I suddenly became very light headed, it was the same feeling as before you faint. I could feel my heart beating so extremely heavy in my chest, I feel as if the other people present were able to see it too. Everything became sort of distant and blurry and I could barely grasp what the other people were saying. Then, every time I would turn my neck to the side it would pulsate and spasm violently. This was all happening and I was trying my hardest to breath and stay relaxed and calm and trying not to make a scene. I wanted so bad to excuse myself but I felt that if I stood up, I would fall over. The only thing I could do was concentrate on my breathing and the cool air coming in from the window. After about 20 minutes I began feeling better and once I started walking I was okay. Ever since however, I've been extremely tired and I have a headache. I explored the symptoms online a little and thought maybe it was some sort of anxiety attack - which I have never had before. The meeting was quite heated among some parents and as a new teacher I was nervous, but not nervous enough to become so overwhelmed - or was I? I sometimes don't realize how stressed I am in certain situations, but it didn't seem all that stressful. About 20 minutes ago, I began feeling some of the same symptoms (the neck and dizziness) but not near as severe. I could be completely off the mark, but any suggestions or ideas on what could be going on - this has never happened to me before. Thanks!
