earlier today i felt a panic attack coming on. my heart rate was all over the place and i felt pretty faint but I remembered reading that placing an ice pack on the middle of your chest and the sides of your neck could stop a panic attack so i tried it and it immediately worked!! my heart rate went from the 90-100 range back down to my normal 60-70 range. apparently it has something to do with a nerve that runs along those areas. i felt so much better afterwards and was able to carry on with my day. ive had GAD and panic disorder for 11 years of my life and this is literally the only trick that has ever stopped a panic attack. just wanted to share for anyone who might need it!!!
