(I forgot about the throwing up part. I was under so much stress at one point, I used to vomit in the morning while trying to get ready for work. Also, I can totally relate to that tingling feeling. In the extremities and stomach which is an indicator that a panic is coming on, making it worse, the shaking, and then it spreading and feeling really cold. It is horrible. I think I blocked it out because it was so frightening. Which of course adds another layer to the panic *sigh* also voices and sounds are so much louder and if I am in a crowded place, I just want to get away. Get away to quiet, and safety).
