Not a doctor, but I've been wrongly diagnosed by, of all professions, an EMT. They have no business diagnosing, but this guy did it. I was suffering from severe stomach cramps, and by the time the EMT's arrived, I was crying and doubled over in pain. When giving him my medical history I included depressive illness. It is, after all, medical. But as soon as I said that, he told me I was "having a panic attack," which I don't ordinarily have, and when I do, stomach cramps are not among the symptoms. Then they got me to the ER where the EMT emphasized to the triage nurse that I had "a history of behavioral issues." The nurse too assumed I was a psychiatric case, and this got me put on the back burner. Fortunately I was not on suicide watch or anything, so after being ignored for as long as I could tolerate, I walked out of there and went to a neighboring hospital. There, I said nothing about mental health and as a result I got my stomach looked at.

I turned out to have gastroenteritis. That's a stomach/intestine infection. Nothing to do with a panic attack.
