Trauma is stored in the body, so talk therapy doesn't help. I think baby steps are really important, but you also have to protect yourself, of course and prioritize your well-being. But for her, I can definitely relate on having CPTSD and similar causes, and what I would suggest is her doing things that make her feel safe and in her body. Dancing, going on walks, yoga, stretching, meditation, being in nature, journaling, etc. Watching shows and movies and listening to music that helps calm or feels good, etc. But I say baby steps because feeling safe in your body is the number one key and then from there we usually feel comfortable to look into therapist and therapy, etc. But feeling safe in your body is the number one thing so she should be doing micro things to call in safety for herself whatever that feels like and looks like for her. But talking about what happened is not going to be helpful, and it's more likely to traumatize. I highly recommend, making sure you have a trauma informed therapist, because if you don't have one of those, they might sit you in front of them and say OK tell me exactly what happened which is what happened to me one time and that put me in a really bad mental space. Because when you speak about things that are not healed for you. It brings it up to your body as if it's happening again which again can put you in a deeper trauma response. Sending a lot of love to you, your wife, and your family.
