Goto both appointments. You never know, one might be terrible and at least you will have another one scheduled without having to wait a long time.

After seeing them, then decide which psychiatric nurse is better.

IMHO no family doctor should be prescribing psychiatric meds. Psychiatry is a speciality, like oncology...and family docs dont prescribe Chemo regimens.

Psychiatric medications require a specialist, with training in that area.

(And I won't even go into the hierarchy of medicine here...but family docs are not on the top)
