Recently I have been trying to take note of every sensation I feel when having a panic attack, and wonder if you would be interested in sharing your feelings too. Mine go something like this:
-Situation where I can't escape easily + negative thought / worry about panic
-Heart starts beating fast and I can feel each beat in my chest
-Start getting hotter and feeling a bit sick
-Pins and needles in arms and legs
-feeling goes into tummy and starts churning
-feeling really weak and sick by now
-Feeling of absolute dread / terror / impending disaster
-Urgent need to go to the toilet.
This is how it feels for me, sometimes if I sit it out it subsides. I am trying to break it down so it isn't so scary.
