I actually rotated in a general practice in the community I have in mind (island, population 8,000) and loved the work, and also the community. Also, it is my fiancee's home. Part of my decision between IM and psych was considering that in IM we could easily go back there--the preceptor I worked with basically offered to give me his practice after residency. And his practice is wonderful, and fun....really a rare thing in this country, and really what I had in mind when I started medical school.
But I ended up ranking psychiatry as my first choice, returning may or may not be an option. It remains to be thoroughly explored, but I thought I would throw the idea out here to see what people say.
One thing I am sure of, which you touched on, would be the boundary issues as a mental health worker in the community, vs. those for a general practitioner. I absolutely loved that people would see me around town and say 'hi' only a week after I was working in the practice, and it was easy and friendly to engage with them.
The second concern that I have is whether or not there would be enough business....which I doubt, considering the population size and the fact that I wouldn't be able to draw from any neighboring areas due to the geography. Not that I am attached to making a ton of money, living lavishly, or needing to be extremely busy, but at least I need to make my loan payments and save for kids education, retirement, etc.
Thanks for your thoughts.
