That's why I bonded so closely with a woman in my first partial program. She was "regular" bipolar, with very high manias, but at the time she was in the group, she was in a very long, very deep depression that matched my own from her descriptions. In fact some of her descriptions, such as thinking of times in the past that were happy, but feeling disconnected to them, like watching yourself in a movie that you never took part in... those were the exact words that I used to describe my feelings while I was an inpatient.
