No worries.
With many disorders there simply isn’t a way to self-regulate / one cannot learn to calm down, like can be done with PTSD. Like bipolar disorder, schizoaffective, psychosis/psychotic, etc.
Some, meanwhile, “get” instant calm by removing the stimuli that’s causing the panic (sensory component disorders mainly, like autism, adhd, etc.), or get immediate lowered levels although it takes a while to reach normal (phobias are a good example); unlike PTSD where once someone is triggered it doesn’t matter if the trigger is still present or not, a person has to learn how to physically manage their response.
Others have to learn to manage / work around what will always be present (including some of the above, and a lot that aren’t), whilst others have lessened symptoms themselves, like PTSD, but using wildly different methods, or some different & some similar methods …but applied very differently. Like OCD.
I’m not familiar enough with Panic Disorder to know where on the ability to learn emotional monitoring & self-regulation spectrum it falls.
