Yes, I agree 100% for sure. The "safe feelings" can be threatened from many angles... but deeper than that... knowing you are SAFE to sleep tonight helps.
Anxiety is a huge "umbrella" with C-PTSD being an extreme form.
I know Sleepy and I have been diagnosed with such... being recent and FOO traumas.
For me it was like being shut in a dome with no windows and no doors for escape... and full on surround sound and real visuals of past trauma events occurred as if they were happening in that moment on repeat.
At one stage it got so bad that I got vertigo with vomiting etc... from NOT avoiding the attacks my mind was visualising.
Like not stepping out of the way, but I knew it was in my mind only so refused to step out of the way of "memories".
That led to an "imbalance" which led to vertigo.
This went on for months and I couldn't drive from the vertigo.
Not much is mentioned about C-PTSD, that it CAN be "cured" ie to live a happy and fulfilling "normal" life whatever THAT is lol.
I mean work and have relationships with friends and or family.
I can go to sleep with a problem on my mind and wake up with a solution.
But during the Courts time at the end of years of it, when everything seemed to be threatened, I had panic attacks in my 40mins sleep. The sweat saturated the bed sheets and I had to strip the bed and use a sleeping bag to sleep in.
THAT was anxiety, the PTSD came LATER hence it's called POST Traumatic Disorder.
Usually develops after the trauma(s).
I fell asleep so early last night, so I'm awake with an aha moment about one "issue" at 3am hahaha.
Already drafted the text... just can't SEND it at 3am lol!
I worked hard yesterday, it's wonderful having the time to do this.
My Chiro asked me what I've been dong bec my back muscles and "traps" are noticeably THERE... I said over 100 buckets of soil and a BRUSH TURKEY I'm shipping to randomx. LOL!
I FINALLY outsmarted the brush turkey! (Better not talk too soon!)
