Your psychiatrist sounds like he/she isn't very sensitive to your needs. Bipolar runs in families, and the fact that your brother has been diagnosed should get your doctor's attention. My father, my sister, and I have all been diagnosed with Bipolar disorder. Your doc saying that if you wonder if you are Bipolar means you're not is ridiculous. When I went through two major eipisodes and was hospitalized during second episode, I, of course wondered aloud to the hospital psychiatrist if I might be Bipolar. My dad and sister had been diagnosed years ago. He gave me a questionnaire, and my results were undeniable. Do you have the option to see a different psychiatrist? I certainly hope so, because you need someone who will LISTEN to you.
