People going through “lows” often feel extremely sad and hopeless. This sadness is different from the emotion that we normally feel.

Bipolar patients can feel extremely sad even if they were in the middle of a party. This is because the sadness they fell comes from a malfunction in the part of the brain that regulates emotions.
