There are a significant number of people diagnosed with depression who don’t get better because they actually have bipolar disorder and have been misdiagnosed or have a mild form of bipolar. I was one of those people. Luckily for me, it only took about 6-9 months to correct the misdiagnosis but for many people, it takes much, much longer. Many people sit with a misdiagnosis of depression for, literally, years. And what doctors (and patients) should be thinking about is if a patient has been diagnosed with depression but isn’t getting better, does he or she really have mild bipolar disorder?
