I have a shrink, and I always recommend a psychiatrist to treat this kind of thing, because these people are MDs with a special knowledge of the biochemistry of drugs
and their effects on both the mind
and body. It is highly specialized experience,
and for this reason, I would not suggest going to a general practitioner.
In my case, my shrink tried me on four (or maybe five?) SSRIs before finding the perfect one, which, for me was Zoloft.
