Screen everything. Today, lots of violently triggering stuff is everywhere. You can't save the world from all of the evil horrible people out there. But you can protect yourself as you stay aware.
Lots of body pain flooding out in various ways. One of the worst is lower back and hip pain. Is this arthritis? My GP says no. But on bad days I have problems walking.
What else happens? Nightmares, adrenalin surges and anal pain. Torture flashbacks. Bad days with anger and wanting to attack everyone. Not knowing what's real and what isn't. You have to focus really hard to try and keep some sense of being grounded.
You have to protect yourself.
