Yeah the same thing has happened to me. I'm seeing a counsellor at the moment who I haven't spoken to about the traumatic incidents because I don't feel safe. I saw a psychologist this year and from the start I said I wanted to work through my trauma. We didn't do this once and I did bring it up; she would act awkward, avoid eye contact and then change the subject. Her reasoning was that because we only had 6 sessions she didn't think it was enough time to work on it, however she only said this in our last session. Should have been straight up from the start about it.
I'm sorry that you've also experienced this

It really sucks, especially because I really do want to work through my traumas.
