I am bipolar and this is completely wrong. People have variable output. Motivation comes and goes. Live circumstances change. People burn out.
These are not bipolar. The name "bipolar" is very misleading. One book I've read has called with multipolar disorder, which is far more accurate. There isn't just mania or depression. There is a whole world of possible dysfunctions that come with it: Anxiety, ADHD, insomnia, psychosis, and the list continues. There can be different moods, stages, and flavors of mania and depression in one person!
On top of this, these symptoms need to be severe enough to impair normal daily function to be diagnosed.
