Hatred against the other sex and against her rivals, hatred against the children whom she could have killed when anger seized her soul.... 74. This is the case of a 30-year-old woman, victim of a remarkable form of jealousy. She is jealous of her home, watching over it like one might watch and protect a beloved. She has an older sister who has been married for five years past and lives outside Vienna. That sister was more to her than her mother or any other friend. She looked upon her as a second mother, confided all her secrets in her and allowed herself to be guided and advised by her at every step. She was supremely happy in her companionship and desired nothing better. She loved only that one sister,—towards the other members of the family she was more or less indifferent. Suddenly the family decided to marry off that sister and an aunt brought a suitor to the house. She found that suitor ridiculous, unsuitable for the sister, and fought with all her limited powers against the match. But the mother showed the greatest eagerness for an early marriage. Then it happened that the girl awoke suddenly in the night. Like a thunder a terrible thought flashed through her mind: “_You must do away with your mother!_” (It was the last desperate soul cry in the attempt to hold on forever to her sister. The mother was the original cause of her misfortune. She could not live without the sister.) The thought so shocked her, the subsequent regrets over it kept her in a very depressed mood. She developed a severe neurosis, consisting chiefly of a series of punishments and expiations to which she deliberately subjected herself. And shortly after that she developed her jealousy of the home. Her sister lived outside Vienna at a small place in Hungary and occasionally came to Vienna. It was natural that she should find a place in the comfortable old home of seven rooms which the family occupied alone. But the girl could not tolerate the sister’s presence in the house. She became depressed, began to cry, found that the furniture was being abused and ruined, could not sleep nights, and daily asked her sister: “How long are you going to stay in town?” so that the sister cut her visit as short as possible.
