Definitely. I suppose it's like an on-call engineer with a dodgy metric that "cries wolf" very regularly. There are hundreds of deadly conditions that have "flu-like symptoms", cancers that manifest in a myriad different ways (from anemia to blurred vision), and other serious conditions that start out as plain old lethargy or listlessness and get diagnosed as depression. I have encountered a complacent doctor who misdiagnosed my sister's cancer as "pain" (??) prescribing pain killers for weeks while the cancer spread and additional symptoms appeared. [Edit: I misremembered as months not weeks, but it was about 6 weeks]. (She died). My father is 95 years old, and had extremely low blood pressure for months, making him constantly sleepy. My mother accidentally made the discovery after she bought a blood pressure monitor for my sister (who has high blood pressure). They took him off the medication, and he's back outside chopping small pieces of firewood and taking short walks. As far as the doctor was concerned he was tired because he was old, and his body was "winding down like an old clock". Too lazy to take his fucking blood pressure. Doctors get extremely complacent, burnt-out, depressed etc. They frequently miss the 1:1000 time that the symptoms are something serious, so I literally never trust a doctor to make a diagnosis without carrying out actual tests. If I'm ever ill enough to need one, I'll have done my own research before visiting one. I don't care if it pisses them off.
