Josie Porter has spoken publicly about the death of her sister Jennifer, a 33-year-old NHS nurse who took her own life after years of hidden cocaine addiction. Jennifer worked successfully at St Richard's Hospital in West Sussex and never used drugs while on duty, meaning her struggles went unnoticed by colleagues and, until she read her diary afterwards, by her own family. Josie has shared their story to raise awareness of the warning signs of high-functioning addiction, noting that outward success and stability can mask serious drug problems.

Jennifer began using cocaine after the death of her grandfather in May 2015, a loss her sister described as devastating, coinciding with her meeting someone who supplied the drug. Josie said she had believed her sister's drug use amounted to occasional benders, but diary entries revealed far heavier use than she had realised. She believes Jennifer's fear of losing her nursing registration, and the shame she felt, stopped her seeking help, and that her death came as a shock since she had recently been making plans, including a trip to New York and concert tickets, with no apparent warning signs beforehand.
