“Just Depression,” They Said — But It Was Lyme Disease After 37 years treating Lyme disease, I’ve seen psychiatric misdiagnosis delay treatment for years. A woman came to my office after seeing three different doctors. Each time, she heard the same thing: “You’re probably just depressed.” But her symptoms told a different story—one that pointed
