From my 50+ years inside this organization, I have seen the viewpoint change with time. A long time ago, the 1960's and 70's, people in general (from what I could tell) did not want to be known as someone who was sent to a *Psych ward.," as we called it.
JWs were wary of "counseling" or therapy... That would mean that you valued what a worldly doctor/therapist could do for you, versus wisdom from God's word.... Especially regarding marriage counseling.
Over time, 60 years, slowly the need for drugs and therapy has become more accepted, as people have allowed themselves to be more educated.
Sometimes, it can vary with where you live.
Hope this helps.
