high intensity exercise, mindfulness/meditation, vagus nerve massages/exercises (lots of videos online), emdr therapy, cognitive behavioral therapy (this needs a good therapist but can probs find resources online). c-ptsd is still relatively new in the dsm-5 so it's still being studied but scientists are currently studying psilocybin (shrooms) and MDMA alternatives to treating it as well. antidepressants aren't really effective, a lot of the trauma is stored somatically so it needs to be released that way. It's not easy by any means and it definitely takes determination/grit to stick by healing. hope you can use this info somehow
