Hypomania:What does it feel like?“At first when I'm high, it's tremendous...ideas
are fast...like shooting stars you follow until brighter ones appear...all shyness disappears, the right words and gestures are suddenly there...uninteresting people, things, become intensely interesting. Sensuality is pervasive, the desire to seduce and be seduced is irresistible. Your marrow is infused with unbelievable feelings of ease, power, well-being, omnipotence, euphoria...you can do
anything...but, somewhere this changes”.

Mania:What does it feel like?“The fast ideas become too fast and there
are far too many...overwhelming confusion replaces clarity...you stop keeping up with it--memory goes. Infectious humor ceases to amuse. Your friends become frightened...everything is now against the grain...you are irritable, angry, frightened, uncontrollable, and trapped”.

Depression:What does it feel like?“I doubt completely my ability to do anything
well. It seems as though my mind has slowed down and burned out to the point of being virtually useless....[I am] haunt[ed]...with the total, the desperate hopelessness of it all... Others say, "It's only temporary, it will pass, you will get over it," but of course they haven't any idea of how I feel, although they are certain they do. If I can't feel, move, think, or care, then what on earth is the point?”
