It hurts to hear people crack stupid jokes about people being bipolar when most of them don't even have any idea what bipolar is or how it affects people. But it seems like people don't want to understand. So yes, it's probably better to keep it to yourself. Sucks it has to be that way, but until people stop thinking that bipolar people are all psycho chainsaw murderers, we should probably stay underground with the rest of the undesirables for our own emotional safety and that of the people we hold close to us, like our children. Nobody wants to be labeled as being crazy and for most people that is how they feel about bipolar.
