Why is it that when we (bipolars) are having a bad mood or a little emotional, we get defined as unstable???

ALL people, have moodswings!!!!
I'm crazy agitated by this and am sick to death of being told to 'calm down' or 'do you need an ativan?'
DUH!! I need an ativan to deal with your ignorant *****!
Meh, feeling a bit angry right now, better watch out or I may go all goofey on y'all.
