Full on melt down then running for 5 blocks as I chased her because it was too overstimulating for her, she spooked and just took off running as fast as she could to nowhere.
Yeah, that along with puking at school.... I have been there; done that. This was my life for almost 10 years and am just starting to come out of it. The body does and the brain can't keep up is how that felt to me. My body was the enemy.
Does she know that she may have PTSD? Have you broached that with her at all so that she has an idea that she isn't actually crazy? I expect that based on what she has (and is) going through, that these reactions aren't crazy - they are learned. That may be a helpful tidbit to know.
I would leave the overwhelming stuff along if you can (?) It didn't matter to me how many times I tried to shore up with exposure therapy, each event just triggered off another trauma reaction - which actually became a trauma in and of itself. Is there a way that you can scale her life completely back Fadeaway?
Also, can you help her learn how to ground to self care (really minimal self care) items? Reframe things so that she realizes any self care is helping her to heal?
Wellness stuff has been a miracle for me, but that may just be me. No idea if it would have helped when I was in the midst of trauma after trauma after trauma.
To be honest, I had to completely scale my life back to literally no stimulation and start over again. I am still in that process. It takes quite some time.
Not sure how your symptoms are playing into this if at all. Ideally you want to be the person she will be able to ground to until she can start taking it on (slowly) herself.
Teaching her that you are calm, watchful (for her signs she is getting jacked up), guiding her towards learning how to help balance out her nervous system (thus her reactions).
I wonder if she was running away from or running to something? I ask because I was always running to my car. That's how I learned what safe was for me.
Also, I have been trying to go swimming (which I love) for almost a year now. It is too much for me too. The noises, the people, the lighting, and oh god, the change room. The echoes.
