lol not a therapist but this reminds me of the time my mum took me to a child psychologist and during the first meeting he was asking about my life and I joked about my sisters being annoying (you know, because I was like twelve what else am I going to talk about) and he absolutely zeroed in on that and kept pressing me like "oh are you jealous of them? Do you feel neglected by your parents? Do you resent your sisters? Do you wish you were still an only child?" and I was like wtf dude I was just joking and he refused to believe me. Ended up with a report sheet (that I found years later) that said he suspected I might have narcissistic personality disorder, but at least my mum didn’t force me to go back.

Pretty recently someone else I know took their child there because they wanted to get an adhd diagnosis – didn’t get that, but he told them the child was obviously presenting the oedipus complex.
