Here are some first-person accounts of the various mood states associated with bipolar disorder:

Depression:
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 haunted with 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?

Hypomania:
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:
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.

Recognition of the various mood states is essential so that the person who has manic-depressive illness can obtain effective treatment and avoid the harmful consequences of the disease, which include destruction of personal relationships, loss of employment, and suicide.
