She was abused by her father the first few years of her life, along with her older siblings, Until her mother finally divorced him and moved out. She was a very intellectual yet anti-social baby, always locking herself up in her room, which greatly annoyed her mother. She was very spoiled, despite her mother having a limited amount of money.
Her anti-social behaviors continued through her childhood, much to her mother's dismay. Her adopted sister, Shelly, became part of the family early into her childhood, and she met her future husband, Anti-Wally, during middle childhood-ish. She became slightly more social,but not by much.
Anti-Carrey was kicked out by her mother when she was in her late teens, her behaviors being too much for her aging mother to handle, She ran away with Anti-Wally and they lived like blue hobos for a while. She killed the leader of the genderbent Anti-Fairies at the time when she was just finishing her teen years, and took control of genderbent Anti-Fairy World.
