Welcome to the Forum, Si P.
I also have been stabbed (twice), survived years of child abuse, and community violence. I know exactly where you are at with the hypervigilance and nightmares with cold sweats. That is me every day and every night.
I'm about to start CBT with the goal of EMDR (eventually, they keep telling me), so I don't have many answers due to my profound ignorance, but I am here reading and I do understand how you feel.
