The story of Fiona Frenzen is not merely a tale of geographic migration from the temperate plains of Denmark to the rugged, volcanic landscapes of rural Iceland. It is a profound narrative of reclaiming a self lost to a decade of over-medication and the subsequent "hell" of psychiatric drug withdrawal. In a recent episode of the Mad in America podcast, Frenzen shared her journey with author Brooke Siem, detailing a harrowing descent into iatrogenic illness and her eventual emergence as a teacher and researcher in one of the world’s most remote inhabited regions.
Her experience highlights a growing global conversation regarding the risks of long-term antidepressant use, the physiological complexities of tapering, and the systemic "gaslighting" many patients face when they attempt to reclaim their lives from chemical intervention.
Main Facts: The Intersection of Trauma and Over-Prescription
Fiona Frenzen, a qualified teacher with a master’s degree in anthropology, spent seven years on Sertraline (Zoloft), reaching a maximum dose of 200 milligrams—a dosage often criticized by researchers for providing diminishing therapeutic returns while significantly increasing the risk of side effects. What began as a prescription for sleep issues and anxiety at age 25 evolved into a decade-long struggle with Obsessive-Compulsive Disorder (OCD) and a host of unexplained physical ailments, including thyroid dysfunction and severe gastrointestinal distress.
The crux of Frenzen’s narrative lies in the failure of the clinical establishment to recognize "protracted withdrawal syndrome." When Frenzen attempted to discontinue her medication under psychiatric supervision, she was advised to "cold turkey" from 50 milligrams—a dose that still occupies approximately 70% of serotonin receptors in the brain. The resulting physiological collapse was misdiagnosed as a "relapse" of her original condition, leading to a "prescribing cascade" that included the addition of benzodiazepines, subsequent addiction, and a three-month hospitalization.
Today, Frenzen lives in rural Iceland, working as a homeroom and subject teacher for over a hundred students. Her recovery, she notes, was not facilitated by further psychiatric intervention, but by the cessation of drugs, the embrace of nature, and the "anthropological" realization that her symptoms were not a sign of an inherent "sickness," but a physiological response to chemical injury and unresolved trauma.
Chronology: A Decade of Chemical Management
The Early Years and the First Prescription
Born in Germany and raised in Denmark, Frenzen’s mental health journey began long before she saw a psychiatrist. At age five, she experienced the profound trauma of her mother’s death. While she lived with anxiety and OCD symptoms throughout her youth, she remained functional without medication until her mid-20s.
In her 25th year, a period of severe sleep deprivation led her General Practitioner to prescribe 100mg of Sertraline. While the drug initially helped her sleep, Frenzen notes that her anxiety simply "shifted" rather than vanished.
The Escalation to 200mg
While living in Germany and working as a teacher, a traumatic event triggered a severe flare-up of OCD. Frenzen became obsessed with the safety of her students, fearing they would fall out of windows. In response, her dosage was doubled to 200mg. Despite the high dose, the OCD remained "stuck" in a loop. Furthermore, her physical health began to deteriorate; she developed thyroid issues requiring Eltroxin and chronic gut inflammation. Clinicians at the time failed to link these systemic issues to her high-dose SSRI regimen.
The "Hell" of Withdrawal
By age 32, Frenzen felt "blocked" and exhausted. She began a taper, but the final "jump" from 50mg to zero—prescribed by her psychiatrist—triggered a catastrophic withdrawal syndrome. She experienced "brain zaps," flashbacks, akathisia (a state of extreme motor restlessness), and profound terror.
"For the first time in my life, I couldn’t be alone," Frenzen recalled. "I’ve hiked the Camino alone; I’ve traveled to America alone. Suddenly, I had so much anxiety I had to walk around my yard in circles for hours."
Hospitalization and the Benzodiazepine Trap
Mistaking withdrawal for a return of mental illness, her psychiatrist prescribed benzodiazepines. Within two weeks, Frenzen was physically dependent. The short half-life of the drug meant she was waking up in a state of "shaking panic" every morning. This led to a three-month hospital stay in Denmark, where she was finally told she could not receive trauma therapy until she was "clean" of the benzodiazepines—a process she describes as being as agonizing as recovering from a heroin addiction.
Supporting Data: The Science of the "Occupancy Curve"
Frenzen’s experience aligns with emerging data in the field of "deprescribing." Researchers like Dr. Mark Horowitz and Dr. Anders Sørensen have highlighted the "hyperbolic" nature of SSRI receptor occupancy.
Data shows that even a small dose of Sertraline (such as 5mg or 10mg) occupies a significant percentage of the serotonin transporters. Therefore, a "jump" from 50mg to zero is not a small step; it is a massive physiological shock to the central nervous system. Frenzen’s symptoms—akathisia and brain zaps—are classic markers of "discontinuation syndrome," a term the pharmaceutical industry often uses to avoid the word "withdrawal."
Furthermore, Frenzen was eventually diagnosed with lymphocytic microscopic colitis, a condition she and her current doctors believe was a direct side effect of long-term SSRI use. This condition has forced her to adopt a strict ketogenic diet to manage severe inflammation, illustrating the long-term "collateral damage" that can occur when psychiatric drugs impact the gut-brain axis.
Official Responses: Clinical Ignorance and Gaslighting
A recurring theme in Frenzen’s journey is the "clinical disconnect" between patient experience and psychiatric training. When Frenzen reported her flashbacks and withdrawal symptoms, one psychiatrist dismissed her childhood trauma, stating it did not meet the "six criteria" for a "big trauma."
This "gaslighting"—the denial of a patient’s lived reality by a person in a position of authority—is a common complaint within the Mad in America community. Frenzen noted that while her doctors saw her as "crazy" and "sick," her lifelong friends saw a woman struggling with a drug-induced crisis.
"My friends knew how I was normally," Frenzen said. "They could see this wasn’t the ‘normal’ Fiona or even the Fiona who struggled with OCD. This was something weird and chemical."
The medical system’s response was consistently to add more medication. It was only when Frenzen took her recovery into her own hands—listening to podcasts and reading research on hyperbolic tapering—that she was able to navigate the "other side" of withdrawal.
Implications: Purpose as a Rehabilitative Tool
Frenzen’s move to Iceland serves as a case study in the power of "functional recovery." Despite the warnings of hospital staff who suggested she move into "supported housing," Frenzen chose to pursue her dream of living in the Arctic.
Shifting the Identity from "Sick" to "Functional"
Frenzen argues that the most effective "therapy" she received was the responsibility of her teaching job. By having to show up for 100 students, she was forced to step out of the "sick role."
"Getting out of this role of being ‘Sick Fiona’… having to be someone for someone else, and having quite a bit of responsibility, helped me more than any other therapy," she explained. This echoes Brooke Siem’s advice to "rehab the brain" by learning difficult new skills, such as a language or a complex craft, to force the nervous system to build new, healthy pathways.
The Anthropological Lens on Mental Health
As an anthropologist, Frenzen now views her "illness" through a cultural and systemic lens. She questions the modern tendency to pathologize grief, anxiety, and the "weirdness" of being human. Her dream is to utilize her master’s degree to research the "disconnect" between doctors and patients in withdrawal, aiming to bridge the gap in medical education.
Her journey has already had a "micro-impact" on the medical field; her sister, a practicing physician, has altered her own prescribing and tapering habits after witnessing Fiona’s struggle.
Conclusion: The Architecture of Acceptance
Fiona Frenzen’s story concludes not with a "cure," but with a hard-won acceptance. She still manages gut issues and occasional waves of sadness, but she does so with a sense of agency.
Her narrative serves as a stark warning against the "just stop" approach to psychiatric medication and a beacon of hope for those currently "walking in circles" in their own yards. By moving to the edge of the world, Frenzen found the center of herself—proving that while the body’s path to healing is long and fraught with "dark winters," it is a journey that can be made, even from the depths of chemical dependency.
