John delves into a hilariously terrifying study about how the blood of people with Bipolar Disorder may be attacking their brains. He also talks about the difficulty of having to say goodbye to his therapist of the past two years. The episode also explores keeping perspective on actions we feel ashamed about, and how to get back on track when we're slipping with our health regiment. Plus, of course, more stories of mania and songs John thought were about him.
