Friend “obsessed” with her therapist and mental health

So my good friend has been in therapy for the past 2 years. She really loves her therapist and talks about her constantly. Like, intimate details of her life, things about their sessions that no one should really know. She brings up her therapist in conversation almost 10x a day. “Alice said this”, “Alice said that”, it’s constant! She will rehash all of her sessions in a text message with me telling me everything about what they talk about and how amazing Alice is. On top of that, she has become obsessed with her diagnosis of an anxiety disorder. She will always use it to justify bad behavior saying things like “lol it’s my anxiety! Alice said it’s normal!” when she will literally be pulling her hair out in an anxiety attack. She will also undermine everyone else who is open with their mental health. We had a friend open up about her post partum anxiety and depression and my friend seriously said “omg, it’s not that bad. It’s not as bad as my anxiety. Let me tell you what Alice said yesterday...”

Like it has become such an obsession! And it’s impossible to talk to her anymore because all she wants to talk about is Alice and her anxiety.
