My therapist called me a liar (kind of)?

I spoke about my sexual abuse as a child that happened with a baby sitter I described how that baby sitter is literally always naked around me all the time and would force me into the bathroom with her.

She asked what the babysitter’s body type is since I mentioned I was drawn to pudgy women and I told her I don’t remember then she said “How come you remember that she was naked all the time but don’t remember what her body looks like? Something isn’t adding up”. Then I was just quiet and didn’t know what to say but I was hurt and blamed myself what if I’m faking my memories? Because she does have a point how do I remember that the babysitter was always naked but not how her body looks? It doesn’t make sense.

Edit: I think she was concerned with her body type because I mentioned that I was drawn to pudgy/chubby women.
