I read a news article about the study and findings and thought well, that explains it. I'm the only one with the offical diagnosis for bipolar but, we've got both ADHD and autism in the family tree. There's some depression, seasonal affective disorder and extreme anxiety but, I always thought how is it that I have bipolar and no one else in my family does? Okay, I'm pretty sure a parent has it but requires no diagnosis so, that doesn't count! What's going on? Yea, I will buy this one.
