To be honest, this raises alarm bells for me. She seems like she can be quite defensive when questioned or challenged. To me that sound like she has quite an ego getting in the way of your therapy and that is never acceptable, therapy is about you not her, she needs to keep herself out of your session. Already you are scared to question her, scared of her response and scared that your feeling might get you terminated. This is not a good basis for a safe secure mutually respected therapeutic relationship.

In my personal opinion, if you have a trauma history then online therapy is not for you. How can she possibly keep you safe or contained thru a chat window? I think you need to find a trauma therapist that you can go see in person.
