Six weeks in, one fixed idea

Hana, 39, has for the past six weeks firmly believed that a former friend has been spreading rumours about her at her workplace, and she has begun avoiding certain colleagues as a result. She describes this calmly and consistently. She has no hallucinations, her speech and affect are ordinary, and she continues to work, though she seems increasingly preoccupied with the belief. No one else in her life shares the belief. This is the first time anything like this has been reported.
