PTSD arises when the normal reaction to traumatic events doesn't stop.

PTSD arises when the normal reactions

to traumatic events don't stop.

And so it's sort of a extended period of time

where one is sort of caught or trapped in the

fight-flight-or-freeze response, which is a normal human --

in fact, every biological creature has that hard-wired,

that response hard-wired into them,

this fight-flight-or-freeze response,

and PTSD arises when that response

is happening when it shouldn't.

And it's oftentimes triggered by events where

you should experience that fight-flight-or-freeze response.
