I got extensively checked out for why I was in pain all the time after I ate, losing massive amounts of weight to the point of near-starvation and felt like I had food stuck in my esophagus all the time. Doctors tested me for a couple of weeks for physical esophagus problems, declared I was fine, and sent me to a psychologist who grilled me for 45 minutes about whether I believed the tests or I "still thought something was wrong with me". I told her I believed the tests but that they were not the right tests yet. Pretty sure I didn't anxiety myself into losing 60 pounds in 4 months and losing my house, work and relationship... she declared I had "health anxiety". Oops, turned out I was actually developing LADA, a form of type 1 diabetes. I ended up at the ER later on and they said I would have died or gone into a coma in another 1-2 days.
