Ellie, you could coach people through difficult medical situations without giving them a lot of advice... frinstance (not one of Betsey's daughter's words, but an invention of my own), you could coach people deciding about putting their kid on meds, or their elderly parent in assisted living. You could coach people through breast cancer or other cancers. You could mentor young docs and teach them better communication skills. You could coach families in hospice.
I think you could do all this as a "former" doc, positioning yourself as a coach and mentor, and not a purveyor of medical advice, per se.
From the way you write and see things, I think you would be phenomenal at this kind of work and it would be a huge service.
