I think bipolar is a "catch all" for some pdocs when they are not sure what the heck is wrong lol. I read like bipolar is suppose to be rare like only 8% or 10% of the population, but read about so many people being diagnosed with some form of BP. The numbers just don't add up.

if you only get depressed, that's not bipolar. I don't like the term bipolar, I like the older term manic depressive better as it better identifies it for me. You can't be bipolar with out the manic part.
