It is late Friday afternoon, and my next patient is Lorna. It makes me uneasy. She usually comes every fortnight on a Tuesday morning, despite my reassurance that once a month is enough. I started seeing her years ago, remember diagnosing her diabetes, suggesting some lifestyle changes which she resisted. From early on she made it clear my role was to prescribe her medications, check her blood pressure, listen to her grumbling dissatisfaction with life.
