I think it depends on the therapy. We do not feel traumatised by our therapist. There are some really good ones out there.
In our therapy we are learning the abuse has already happened. It is over. We don't have to relive it over and over again. It's done. Our T helps us learn ways to keep the past in the past, and our feet in the present. And also to bring the ones who are stuck in the past into the present with us.
It is done. It is over. They don't need to live through that loop anymore. Life is different now.
We are finding this is so much better than getting triggered all the time and finding ourselves hijacked from within.
Maybe one day you can find a way into the present for all of you too.
