Finding a good human therapist match is difficult, and it's far more difficult for people who are neurodivergent in any way. If a therapist isn't experienced in the way ADHD or autistic brains work differently they often simply don't have the mental model required to understand and help at all and they give advice that's completely inappropriate. They might have worked with a lot of OCD people, but they won't really get it unless they truly specialize in it or are afflicted themselves. Most of the popular depictions of mental differences, and even many of the perspectives in medical literature of them are wrong or use technical language that's terribly easy to misunderstand out of context. I'm terrified to think about the misconceptions that an LLM would have after ingesting all the Internet content about mental differences/illnesses!

And it's not just having a good mental or virtual-mental model of an illness, personal circumstances also make all the difference. A human therapist learns about your personal circumstances and history and learns the ways that your individual thought patterns diverge from the norm and from the norm of people whose brains differ in the same way as yours. LLMs as they are now don't incorporate memory of past conversations and will never be able learn about you to customize their responses appropriately!
