I have an excellent GP, but he does not feel well-versed enough in the nuances/interactions, etc. of psych meds to handle more than mild to moderate depression and mild/moderate anxiety. He was very upfront about that from the beginning, and as soon as it was clear my issues were more complicated than the above, he insisted I see a pdoc. My pdoc's vast knowledge of psych meds and how they can be used in combination, etc. is vastly superior to what my GP knows, and he realizes that.
