Ciran

A Cancer’s personality is like wading chest deep in a lake of warm water. It feels sparkling and cool while you're in the shallow end, but you know that if you were to dive in, it would feel warm.
The self-awareness of a Cancer is like the tides–constantly moving in and out of focus. Their personalities are layered. Cancers have many moods, some of which are contradictory, but they also have a deep, core self that persists.
Cancers are weighed down by their own sorrows and the sorrows of those around them. They are frequently haunted by grief. It’s hard for them to share their pain with others, and they are often afraid to be vulnerable because they carry a fear that people will use their weaknesses against them. Cancers have learned to hide their pain to avoid burdening anyone else. They pretend they’re okay when they’re not.
Their emotions are like an exposed nerve. Cancers can feel everything. They’re like a tuning fork that vibrates at the slightest provocation. They tend to carry deep grudges because they can’t forget the emotional sting of even a slight.

In mythology, Cancer is associated with the crab in the story of the Twelve Labours of Heracles. In the myth, Hera sends the crab to distract Hercules while the hero is fighting the Lernaean Hydra, the serpent-like beast with many heads and poisonous breath. When the crab approaches Hercules, the hero kicks it all the way to the stars.
In another version, the crab gets crushed instead and Hera, a sworn enemy of Hercules, places it in the sky for its efforts. However, she places the crab in a region of the sky that has no bright stars, because despite its efforts, the crab was not successful in accomplishing the task. Cancer does not have any stars brighter than fourth magnitude.
