Please try the grounding strategy shared recently. I have panic attacks, too, and that is what you are having.
Lookup now, do this, while breathing a little deeply...
Find 5 things you can see. Name them.
Find 4 things you can touch. Touch them.
Find 3 things you can hear. Identify them if you can.
Find 2 things you can smell. Identify.
Find 1 thing you can taste. (Chocolate can really extend this moment, I find!)
