Cork woman: ‘I lost everything...now I’m the happiest I’ve ever been’

When you meet Jennifer McCarthy, one of the first things you notice is her energy.

She laughs easily, chats comfortably, and has the kind of warmth that makes people feel at ease almost instantly.

The Cork woman, now living back in Ireland after spending 25 years in the UK, is known by many for her positivity, her work in health and wellbeing, and for always seeming to find light in difficult situations.

What most people would not know is that behind that positivity lies years of heartbreak, illness, grief, and survival.

Over the course of just 16 months, Jennifer experienced the breakdown of her marriage, the loss of her career, the death of her mother, the passing of a close friend and colleague to breast cancer, and her own diagnosis of breast cancer.

Eventually, she made the decision to return home to Ireland and start again with her two daughters.

Looking back now, Jennifer says there was a time when she felt she had lost absolutely everything.

“I was like, oh my God, I’ve lost everything, including my identity. Who am I?”

At the age of 18, Jennifer got on a plane and began building a life in the UK, where she studied before going on to work as a cardiothoracic specialist nurse and trauma nurse, later fulfilling her dream career as a police officer. She was raising two daughters and had what many would consider a settled family life.

Then her mother became seriously ill.

This came not long after Jennifer had been involved in a serious road traffic collision while on duty. It left her physically injured with ongoing pain, while dealing with the uncertainty surrounding the future of the career she loved.

Jennifer found herself trying to navigate caring for her mother while continuing life as normal, but losing a parent changed everything.

She admits she is still unsure whether being present in those final moments would have brought comfort or more pain.

“My family were there, and sometimes I’m envious of that,” she said. “But then part of me thinks I’d spent so much time with her already, maybe I didn’t want to see those final moments.”

Only 48 hours after burying her mother, Jennifer flew back to England.

However, her marriage was beginning to suffer problems.

Looking back now, Jennifer says she never truly had the chance to properly grieve for her own mother while everything else around her was collapsing. She remembers questioning herself constantly and trying hard to save the marriage.

Around this time, she remembers cycling in heavy rain and looking to the sky.

“I said, ‘Mam, if there’s ever a time you can help me, just give me a sign that I’m not losing the plot.’”

Around this same period, a friend and fellow police officer had died from breast cancer. Jennifer had missed the funeral because it took place on the same day as her own mother’s burial.

Soon afterwards, after 18 years, her marriage ended.

Despite the pain, Jennifer had to compose herself for her daughters, and also stresses that her friends and colleagues were incredibly supportive and protective of her throughout her ordeals.

Then another devastating blow arrived.

Just six weeks after being medically retired from policing, Jennifer discovered something unusual in her breast. She describes it not as a lump, but as feeling like “a slug”.

Initially, she dismissed symptoms like tiredness, explaining she was a single mother and exhausted anyway. Medical tests followed quickly.

Sitting in a hospital room, Jennifer saw a team of specialists enter together. Because of her years working in both nursing and policing, she instantly recognised what that meant. “I’d sat in rooms before where families were told life-changing news.”

Then the consultant spoke.

“Jennifer, it’s not good.” Her immediate response was: “How long have I got?” Doctors explained she had breast cancer, which had spread to her lymph nodes.

Even now, Jennifer says she remembers very little from that appointment. What she does remember is making an unusual decision.

Rather than going straight into treatment, she booked a holiday. Within days, she packed her bags and brought her daughters to Bulgaria.

“They had absolutely no idea,” she said.

For one week, her girls laughed, swam, and enjoyed sunshine while Jennifer quietly carried the knowledge that urgent surgery awaited her at home.

The day after returning home, treatment began, and Jennifer entered a period of surgery, recovery, radiotherapy, physical pain, and mental exhaustion, all while trying to shield her daughters from the reality of what was happening.

Her girls remained unaware of the extent of her illness because Jennifer was determined that, despite everything, they would continue to feel safe.

At one stage, Jennifer remembers lying on the couch crying, without enough energy to even make herself a sandwich, yet still feeling too proud to ask for help.

Looking back now, she says not asking for support was one of the biggest mistakes she made.

“If anything happened again, I’d ask for help,” she said.

Her advice to others is straightforward but powerful. Strength, she believes, is not carrying everything alone or pretending to cope when you are falling apart. Real strength is allowing people to step in, accepting support, and understanding that vulnerability is not weakness.

Her daughters, she says, have experienced more than most children ever should.

By this point, Jennifer had reached another major life decision.

She would leave England and move home.

During the covid lockdown, she sold her house, bought a property in Ireland without viewing it in person, and packed up her life with her daughters and dog.

“When the ferry landed in Dublin, I thought, this is it, we either sink or swim. It’s our new life.”

Starting again in Ireland meant adjusting to new schools and new surroundings, and creating stability after years of upheaval.

Slowly, something shifted. Her daughters flourished. The fear and uncertainty that had followed the family for years gradually gave way to happiness and routine.

Two years ago, another serious health crisis followed when complications during surgery caused her heart to stop twice. She spent time in intensive care and once again found herself relying heavily on family and friends.

One day, her eldest daughter said something Jennifer will never forget: “This is the happiest I’ve ever been in my life. I’m so glad we moved to Ireland.” 

Those words stayed with her because, despite every difficult decision and sacrifice, Jennifer says her children remained at the centre of everything she did.

Today, five years after returning home, success means something entirely different than it once did.

For Jennifer, success is no longer measured through career progression, achievements, or status. Instead, it is found in peace of mind, calmness, laughter and the ability to go to bed at night knowing her children are happy.

“I’m the happiest I’ve ever been,” she said.

That happiness, however, has not arrived easily. It has been built slowly through grief, illness, heartbreak, and survival.

Perhaps the most powerful thing she shared was a reflection on everything she has survived:

“My life didn’t fall apart by accident,” she said. “It forced me to rebuild it properly.” Then, after a pause, came the words that seem to capture her journey best: “When you feel like you’re broken, you’re not. You’re starting to rebuild.”

For Jennifer, healing did not come from pretending life was perfect or ignoring difficult days. Rather, she says the smallest things often became the most important: sea dips, saunas, long walks with the dog, coffee with friends, laughter, and surrounding herself with positive people.

Her message to anybody going through a difficult time is simple: speak to people, reach out, ask for help, and never feel ashamed to go to counselling or therapy.

At the end of the interview, Jennifer also spoke about using her experiences to help others through public speaking and coaching.

She now delivers signature talks titled From Scrubs To Stab Vests, where she speaks openly about trauma, resilience, rebuilding after adversity, and the realities of working and transitioning both in and from nursing and policing. She also works in life coaching and health and wellbeing advocacy.

Jennifer McCarthy knows what rock bottom looks like.

More importantly, she knows that even after the darkest chapters, it is possible to build a life worth loving again.
