With respect to the OP, how about this: psychiatrist/psychologist/neurologist etc., heal thyself.
There are many celebrity, and no doubt non-celebrity, mental health specialists who themselves have, often severe, mental health problems. I’m thinking here of the likes of Oliver Sacks. Oliver Sacks could not recognise faces, for example, and at parties, even his own family had to wear nametags for identification. Oliver Sacks was unable to cure himself.
A few years ago, I attended an out-patient clinic. I was seeing a medical doctor, not a mental health specialist. When I entered the room, the consultant was sitting at his desk staring at the screen of a computer whilst occasionally typing. I was invited to sit down by the nurse, not by the consultant, who still did not look at me. When the consultation began, he observed no social courtesies such as introducing himself. Instead, glancing at me briefly, he launched into the consultation and started asking me questions. Since he was reading these questions off a screen and then typing in the answers, he did not look at me. This consultant was displaying typical signs of autism.
Autism is another condition which mental health specialists are unable to cure. For example, psychologists have claimed that around 95% of the population is autistic. I believe that the percentage has increased since I last heard.
As far as I am aware, there is no mental illness, or at least very few mental illnesses, that the medical profession can cure. They may be able to alleviate symptoms, but that is a far cry from a cure. ( In fact, alleviating the symptoms without understanding their cause is likely to make the patient worse, not better.)
Therefore, as to the future of mental health treatment, since physicians are unable to heal themselves, there IS no future.
