For me things like feeling trapped, claustrophobia.
Other things such as feeling dizzy,breathless,being alone.
Then the health anxiety stuff, like tight throat,lip numbness, chest pain, you know bodily symptoms that I think the worst of or fear they will get worse.
The health anxiety makes me nervous due to being far from a hospital and not having transport.
Also makes me scared to be alone, or too far from a "safe" place.
So for me most of my panic is caused by bodily symptoms, fear of being on my own and then feeling trapped/claustropbic.
I was always a worrier.
I've been clustrophobic since I was a child, hated crowds and elevators.
I used to walk home from school alone about age 10, I had a fear of this big dog lol so I'd be scared in case I met it.
I think that's how the agoraphobia started.
My mum got sick and almost died, that started off the health anxiety. But I also blame the media, magazines always had horror stories in them!
Basically ignorance was bliss
I've had some bad side effects to meds, including hallucinations, uncontrollable shaking, paranoia and sucidal thoughts. That made me phobic of meds, which then made me scared of having an alergic reaction to pretty much anything and everything!
I also had a bad sezuire once, spent a few days in the ICU in hospital.
Afterwards everyone made sure I wasn't alone in case it happened again.
So that added to my fear of being alone :(
Also anxiety runs in my family, my mum is the nervous worrier type and my grandmother has mild health anxiety.
I've got some cousins with phobias and OCD and some other family with depression.
