I use to have panic attacks every day about 20 times a day. But they weren't out of the blue for no apparent reason. I would have a panic attacks everytime i would start to get really paranoid. Like, if i took a bite of food and it tasted strange, i would think i was being poisoned and start panicking.
The panic attacks made me feel like i was dying. My throat would feel like it was swelling up and i'd start hyperventallating, heart would be beating really fast, i;'d be sweating and all that. I remember telling people to take me to the hospital because i was dying of poison or something like thatl, but really it was just the panic attacks.
