The elders have a one size fits all solution to everything, more prayer, service, meetings, study. It's a tragedy in this day and age that they are so ignorant about mental health, it's equivalent to them trying to perform brain surgery because they had a week of training in it. Anybody with any mental health issues should be encouraged to consult a mental health professional. There are always government programs for lower income people so there is no excuse to allow people to suffer like that. Even a mainstream religion that has paid and educated clergy would not attempt to treat anyone with schizophrenia or other major mental health issue. There are much better drugs and treatments these days, these people could be helped and lead fairly normal lives, instead they are no better off than if they lived 100 years ago.
I knew of a case where a woman with severe mental health issues, schizophrenia I think, who went of the rails and had an affair among other things. Of course they disfellowshipped her. She then started cutting herself, attempted suicide, took drugs, complete and utter melt down. Everyone in the hall thought she was demonized. She was finally hospitalized and given real treatment, she stabilized and got reinstated, then stopped taking her medication and started the whole thing all over again. She had young children, who knows what happened to them. I am sure there are many cases like this.
