Therapist Not Getting Bigger Picture With Parents

[Justmehere]

I told her how I don't want to be around my father and how I find him scary in general

I've told her I feel very uncomfortable about the whole topic in general I mentioned my issue with my parents

This is fairly vague and indirect. I'd try being more direct and much more specific about what you need in therapy. If you need to, bring in a list for her to read. Something like...
1.) I would like to focus on the event for which I have memory loss.
2.) I do not think you understand the bigger picture with my family. Can we look at that again?
3.) I do not want to spend time on developing a romantic relationship as the solution to my symptoms. Can we focus on other tools to manage my symptoms?

This will help her help you... or help you know better if she can't help with these issues.
