This emotion is a stress response.
You might even recall the event so vividly that it almost feels as though it’s still happening.
This is because the emotion (stress response) that is generated in the body is real and the memory of the event being re-experienced is as if it were happening in the present tense.
BUT something that is imagined or remembered in your brain – but is not actually happening now – is in fact a fantasy.
In other words, resentments are fantasies that continue to cause us pain and make us suffer.
