Looking at all these posts, I guess I'm the odd duck... but I suppose if you look far enough up anyone's family tree, you won't find traces of BP. It has to start somewhere.

I'm the lucky one who starts BP in my family tree!

On a side note, this is partially why my pdoc was so hesitant about my BP diagnosis (and why I had a hard time accepting it). He said that BP tends to run in the family, but I have no family history.
