I 100% guarantee the therapist doesn't encourage it the way she says they do, tons of these mentally ill fuck ups always say their hyper-obsession with stuff is "Totally signed off by their therapist" but can't explain how or why in any verbose way, also what therapist actively encourages a patient's delusions (Troon points inbound in 3...2...1) when it's like this?
I imagine anytime anyone tries to confront her over this and pull her away from it she just twists everything to make it sound like she's in the right and totally normal for this, it's being childbrained to a seriously unhealthy degree.
