Nurse Jennifer "Jenn" Porter, 33, tragically took her own life after secretly struggling with cocaine addiction while building a successful nursing career. Her sister, Josie Porter, 32, has spoken out to reveal the hidden signs of high-functioning addiction.
Addiction Masked by Success
Jenn, from Southsea, Portsmouth, worked as a respiratory nurse during the Covid-19 pandemic. Her family never suspected she had an addiction, believing she simply enjoyed occasional "benders." Josie later discovered through Jenn's diaries the extent of her cocaine dependence and its severe impact on her mental health.
Josie said: "It genuinely looked like things were improving. She'd bought a new phone, had deliveries on the way and concerts booked. That's why it was such a shock - I just didn't expect it."
The Perfect Storm
Jenn started using cocaine after their grandfather died in May 2015. Josie explained: "He was our main person growing up. My dad wasn't really around and when grandad died it hit Jenn really hard. Around the same time she met someone who was selling cocaine and suddenly she had easy access to it. It was the perfect storm."
Despite her addiction, Jenn qualified as a nurse and worked demanding shifts during the pandemic. Josie said: "She was incredibly dedicated to her work and would never go in when she had been on drugs. She worked nights, dealt with understaffing and carried a huge amount of responsibility. There is a lot of pressure in that work and I think the drugs become a cushion."
Deteriorating Mental Health
In 2019, Jenn made a serious suicide attempt. She received crisis team support and antidepressants but continued battling depression, grief, and addiction. Her family missed red flags, such as her disappearing for days at a time. Josie said: "We'd go out as a group and she'd disappear for days at a time. It became a red flag, but we didn't think she was addicted - we just were thinking she must like a bender. I never thought my sister would be an addict."
Shock of Suicide
When Jenn died by suicide in June 2025, it shocked the family because she seemed happier beforehand—paying debts, making plans, and booking events. Josie, a dietitian from east London, now believes apparent improvements can mask struggles: "Sometimes when people seem better, that's actually when they need the most support."
Reading Jenn's letters revealed the addiction's toll: "I used to think of cocaine addiction as a physical thing... After Jenn died, we found letters and diary entries that showed how paranoid and suicidal she had become. It completely changed my understanding of what addiction can do to someone."
Challenging Stereotypes
Josie hopes sharing Jenn's story will challenge addiction stereotypes and encourage open conversations. She said: "When people think of addiction, they often picture someone who has lost everything - no job, no family. You don't imagine a successful nurse with a career and a home."
Jenn's inquest, attended by family and eight friends, recorded a suicide verdict. Josie added: "Jenn was an incredible nurse who spent her life helping other people. We've lost someone truly special. If talking about what happened helps even one family recognise the signs or encourages one person to ask for help, then it's worth telling her story."
