I hope you don't mind me commenting as I am not of that gender to qualify as an elder.
The problem as I have observed is that the "counsel" the elders give, can make mental illness worse.
The last thing a sick person needs is a side order of guilt and shame, which is the only flavour WT counsel comes in.
And no, the elders are not in any way, shape,or form qualified to advise anything other than
" I would advise you to seek medical advice, as I am not qualified in these matters"
If an elder doesn't feel overwhwelmed and unqualified when counseling the mentally ill,
then they are overestimating their own ability and qualifications.
Last time I checked the borg were'nt in the business of handing out diplomas in psychology.
These guy's are clueless and shouldn't be put in the position of psychologist/therapist/marriage counselor/spiritual policeman/lecturer etc
