I agree with raven on this. So many things can mimic Bipolar behaviour, doesn't mean a person is.
Seems lately, thanks to negative things being blow out of proportion with the media,movies,etc. "Bipolar" has become a "catch all" for stuff, for awhile "ADD/ADHD" was the public's "catch all".
Sad to hear people so ready to self-diagnose or others mis-diagnose.
It's best to have an evaluation from a psychiatrist(s) to be properly DXed, try not to fill yourself with added anxiety by "wondering if's", that media,internet,movies,etc. can induce.
Take care,
