The incorrect use of the word bipolar.

So today I was watching this new show that premiered on Nickelodeon. Yes, I'm 18 and still watch Nickelodeon. Anyway.. The name of the show is "Victorious" starring Victoria Justice. I was watching it and it seemed like pretty much any other Nickelodeon show, UNTIL.. she used the word bipolar when not referring to someone who IS actually bipolar. So I wrote on the message boards for the show and after I clicked 'Post', it said that the people would have to give it a "thumbs up" before posting it. I'm not sure if they will because they might think it's inappropriate but I think it's perfectly fine to write that if they are gonna use it. The exact line on the show was, "Oh ya, like regular schools have improv classes with barefoot teachers and nerds with puppets and Bipolar Cats and mean girls who make you bark like a dog?". By the way, one of the girls' names is Cat. And just because she's different does not mean that she is bipolar. She had not said that she was bipolar, and she did not act bipolar. When the main character Tori was asking her a question, she has said, "Well my name is Cat" and Tori responded with "oh like the animal?". Then Cat was acting as if she thought people would judge her or whatever and responded something like "Why? Do you think that's weird?" And she looked really worried as to what people thought. So the show must of figured, oh let's just add the word bipolar when we talk about her later because she's different. And I'm surprised that Nickelodeon would allow that! People just throw around the word now like, "Oh, you're so bipolar." and it's like saying, "Oh, that retarted." I highly doubt that Nickelodeon would EVER allow a show to use the word retard. But people don't care about the word bipolar. They think it's fine. Well, I AM bipolar and I think that it's offensive for them to just use it like that. Because people who say that, dont' know what it's about. I have to live with it everyday for the rest of my life. So if you don't know what it is, don't use the word!! Simple as that!
So if anybody knows a way to contact Nickelodeon, let me know!!.
I would gladly write them an email discussing my anger. And maybe I'll get a retraction or an email saying sorry. I just think that it's really surprising to see this in a kid show and have them see nothing wrong with it. Have people really gotten that stupid and selfish that they think it's ok to use it like that in real life and write it into a TV show?
And if they do post my message, I will copy and paste it in the comments. I forgot to copy and paste before, and I can't find it, or remember what I wrote... so hopefully they put it up. :)
