Cancer is ruled by the Moon, and you carry her tides in your nervous system. You feel things at high resolution. You sense the unspoken in a room before anyone says a word. Home, family, and emotional safety aren't cliches for you — they're the structure that makes everything else possible.
The shadow of Cancer is moodiness that becomes withdrawal, and the use of guilt as a weapon when you're hurt. The mature Cancer has learned that feelings don't have to be acted on immediately, and that vulnerability shared cleanly is a stronger bond than vulnerability used as leverage.
You'll recognize yourself in Cancer if you remember every emotional slight from years ago, if you cook for people as a love language, and if you have a strange kind of psychic radar for who in a group is hurting.
