For some reason bipolar sounds less scary. But on the other hand it makes it easier for people to flippantly say oh I'm so bipolar today if it's someone I know I ALWAYS challenge them ask "are you really bipolar? Because I really am, and trust me, you don't wanna go there!" I then take an opportunity to do a little education into mental illness and explain how it's so hurtful when people take it lightly like it's no big thing, just a couple of mood swings.
