That sounds like a really distressing experience @FringeDweller I imagine it's left you feeling out of control and as though a boundary has been crossed all over again.
That fear of not being beieved is unfortunately all too common. You did so well to disclose your experience and to make the decision to seek suppot too. Not at all easy to do.
Sometimes, counsellors and psychologists, being human, can make mistakes. It can feel so hard to do, but one of the best ways to manage situations like this is to let your psychologist know how you're feeling about the situation and the impact it's had on you. It's so important that you're able to feel heard and understood around this stuff and hopefully with a bit more understanding, your psychologist will be more mindful to include you more in any decisions made about your treatment going forward.
