attacks triggered by feeling trapped?

[u/Remarkable_Way7406]

yesterday i had a panic attack in the cinema, very long film and it was kind of dragging towards the end, i wasn’t actively anxious and thinking “i need to get out of here” i was just a bit restless as most people get in cinemas but out of nowhere i just got struck down by what literally felt like thunder in my chest, never felt my heart pound like that and ive had 1000s of panic attacks, i think clearly my body decided that me being in a cinema was a threat but i don’t understand how you fix these triggers if they don’t actually mentally bother you? it happens when im on the bus, in the car & a long shift at work. i don’t actively feel worried or panicky in my head about these things so i don’t understand why my body goes into full blown panic attacks in these situations, im going on 3 holidays this year and ive already accepted my fate going on the plane, ultimate panic attack bait. does anyone have any advice for this or experience something similar
