((((((Zoo)))))) I have thought a lot about what to post to you on this.
You have had so much pain in your life. And you try so hard to do what you need to do in order to heal. I applaud you for that.

Here are my views on this.
1) No matter how recent the trauma, it is NOT the fault of the one who is being hurt.
It is NOT your fault. Period.

2) That T does not sound like she needs to treat you for trauma. Trauma therapists are different. They use the DBT and CBT skills, but the interaction with the client is very different. And many Ts (like mine) who are trauma specialists actually know that it is sometimes VITAL for a client to have a T on a long term basis. There is nothing at all wrong with that type of a relationship. Even my T has his own long-term T for his trauma.

3) Trauma and PTSD can be healed up to the point where the effects on the survivor are very minimal. Even when new trauma happens, we learn how to manage the impact. We learn how to reach out for the support we need. Telling a client that they have to "live with it" is not acceptable.

You DESERVE your wellness.
You DESERVE a T who is trained in trauma recovery and PTSD.

Also ask about EMDR therapy. That is what my T is using on me and it has made a HUGE impact for me.
You can do this. You can make it.
