Desire led to Despair. My fleeting moments were passion, which I desired, yet desperate, hence despair.
Fiction follows: (source: wikipedia: endless: desire|despair)
Desire is the third youngest of the Endless and the twin of Despair. It is a strikingly beautiful figure whose gender is mutable, becoming male, female, both, or neither as the situation warrants. It is often referred to as "sister-brother" by its siblings, particularly Dream. Desire blends in effortlessly with whatever environment it finds itself in. It lives in the heart of a massive flesh-and-blood statue of itself, known as the Threshold. Indeed, further strengthening the connection to hearts, Desire's sigil in the galleries of the other Endless is a heart of cut glass.
Desire is described as being of medium height, smelling faintly of summer peaches. Desire casts two shadows, one black and sharp, the other translucent and wavering. Desire's smiles are brief and sharp. Its skin is "pale as smoke," and its eyes are "tawny and sharp as yellow wine."
Desire is easily the cruelest of the Endless. It seems obsessed with interfering with the affairs of its elder siblings, particularly Dream. The motivation behind this is not clear, but seems to be simply a variation on childish teasing. Desire is not exactly unaware of the consequences of its actions, but considers those consequences ultimately unimportant, a position which angers Morpheus and Death in particular. Desire sometimes acts in concert with Despair and Delirium; the relationship is not clear, however, and Desire is much more distant from its siblings than Despair or Delirium.
Despair is the twin sister of Desire. She is squat, flabby and pale-skinned, with black hair, gray eyes, and pointed teeth. Her voice is little more than a whisper, and she has no odor, but her shadow smells musky and pungent, like the skin of a snake. She does not wear clothes. On a finger of her left hand she wears a ring with a hook attached to it, with which she habitually carves her flesh. The hook is her sigil in the galleries of the other characters. Her realm is a gray space in which floats a white fog and countless mirrors, which are connected to mirrors in the human world, through which she looks on those who are in despair. The only other inhabitants of her realm are her pet rats.
