I'm the only one with a bp dx, though I suspect that my mom might be cyclothymic. My brother is depressed and suffers from OCD and ADHD. I'm scared that he'll end up bipolar, as he claims to have times where he feels "on top of the world" in addition to his depression. Bipolar is one of the most heritable of mental illnesses, so it's interesting that I don't see more of it in my family.
