Can I have a female character meet a man and become obsessive to the point of destruction in a short story? My female MC meets a man she can't have, and slowly creates a reality where she feels they are madly in love, even though he has never/will never meet her. She starts out with a desperate need for a love that won't hurt her and this man falls in her lap. She latches on to him and slowly slips into madness, shutting out her friends and losing her job, all in an attempt to stay with the one she loves. The question is, could this be pulled off in a short story or is this too big? I've heard that a short story should only cover at most a couple of days but this would take longer than that.
