I get you're still bent from not getting into psych but stop the misinformation. If you think you are trained well enough, then you'd be a fool to not open a clinic seeing psych patients when you are done with FM residency.
PCPs prescribe the majority of meds for the majority of conditions (cardiac, GI, endo, ID etc). It's their job to be comfortable with many different diseases and generally be the first point of contact for patients and provide ongoing chronic care. It doesn't mean PCPs are the experts. And waiting for a pt to get "actively" psychotic prior to referring to psych is bad, bad medicine.
At the same time, there is a range of mental health conditions, patients, and services. PCP, NP, publicly funded clinic, PP insurance psychiatrist, PP cash pay psychiatrist, inpatient hospitalization, partial hospitalization, detox, prison, SW, MSW, PhD, and even cash pay Walmart counseling fill different niches. Not everyone requires a PP psychiatrist and not all patients are appropriate for a PP clinic.
