I actually developed a very strong passion for bipolar disorder through a book my pdoc recommended me (prior to my bipolar diagnosis). I loved the disorder and my pdoc revealed the diagnosis following a SPECT scan. Turns out he had wanted me to know about the disorder and come to terms with it, as he suspected it, before giving a diagnosis, so I was surprisingly excited to find out I was a bipolar. I continue reading about it and enjoy keeping up with the latest research
