Why is the term bipolar being used over exaggeratedly?

[English]

Ther has been a lot about bipolar and even myself have been reading up on it just because I hear people say it so much. It is said it is over diagnosed. Many patients think it is now a "go to" diagnosis if the doctor is not able to spend much time on your case and has a degree of uncertainty. Basically, they HAVE TO put in a code on a form for a persons insuance papers. This maybe why some doctors change their own diagnosis at a later date???? It is also kind of a slang term now for anyone who is angry at anyone or anything even if they have good reason to be. I guess people with bipolar can thank the media for a propetuating a another false stereotype?????
