What it was, something happened yesterday of the "fill out a police report" kind. It triggered the PTSD, I didn't complely lose it, thanks to coping skills I learn for that but my brain went numb and I dropped everything drove home and buried myself under the blankets and wasn't feeling safe. But that doesn't mean I'm depressed or suicidal, it just means I have some high emotions to deal with. My basic mood Is still stable. For me the clue was the trigger, that is emotions.
