I was a jw in the 1980's and getting help with mental illness was generally frowned upon. My jw husband was first a suicidal maniac and later a homocidal maniac, and I consulted with a medical doctor who was also a jw elder. Once he activated forced committment to a mental hospital, the elders seemed okay with it. The elders in two different congregations that we attended actually encouraged him staying on his meds and keeping appointments with his psychiatrist. Upon the first forced committment, he was diagnosed as schizophrenic.
Unfortunately he didn't stay on his meds and was forcibly committed to a mental institution for a second time. I suffered years of physical abuse at his hands, and my life was also threatened. What is terrible about the Watch Tower in the case of mental illness is that spouses of the afflicted are supposed to take the abuse and stay quiet about it. Even after my jw husband's psychiatrist said that he would probably follow through on his death threats to me, and a judge agreed and signed the forced committment order, the elders tried to bully me into staying in the marriage.
One thing to note about the mentally ill in the organization is that if they see a counselor or psychiatrist who is a jw, they must sign a waiver of privacy. So there is no doctor-patient confidentiality. If the afflicted jw confides committing a sin, the jw therapist will report such to the elders. There have been posts here on JWN about that, but I can't recall which ones they are. Please try to keep your jw relative away from jw counselors.
