You know many bipolar people who are not violent. You just don’t know that they are bipolar.
The classic bi-polar—that’s the type I have met. And yes I know they are bi-polar because they are kind enough to warn people that they have the illness. My first experience was an eye opener for sure.
If I have met others I probably met their acquaintance on an upward crest. The one’s I found out later were bi-polar are fun when they rev up.
