At certain times on and off my father was stalking me - so CBT that I am fine is not appropriate. Currently my sister's ex has threatened me but he would have to find me first and I move around so much, it would be unlikely. So CBT that I am (on the whole - Barring alien abduction (almost no probability but high consequence) and barring sister's violent ex and he would have to drive to where I live, and then wait for me to turn up which he won't do because he works in a Catholic School, and is a drug addict as well, and is busy terrorising my sister and their children - so he is time poor) but I am pretty much safe. I know with my (potentially advanced) CBT I can confuse the Borg.
Seriously though it takes so much time for me to come down from that hypervigilance and be in this now. It takes a lot of concentration. Which means all the Ps really come in to play. Perspective, patience, practice, perseverance, etc really need to come into play.
