Every single cell in your body feels as if it will explode.
Your heart beats faster than seems possible.
There is at once a feeling that you are falling from a great height combined with the sensation that you are being hurtled through thin air in the upper levels of the atmosphere.
Your shoulders tighten and jaw clenches.
Something in your stomach feels like it’s swirling around rapidly, like the blue water in the stainless steel toilet bowel on an airliner at 30,000 feet when you flush.
Limbs tingle, and feel like they might move uncontrollably.
There is a sense that the blood in your veins to flare up and rage in a violent boil at any moment.
Your breathing becomes short and quick.
A tingling sensation starts in your stomach and rises like the bubbles in a bottle of seltzer water, up through your throat and neck. Some of these bubbles seem to be released just below your nose — the rest rise up through your skull and are released out the crown of your head.
This is a panic attack.
