Suffering has always been at the table of Francisco Alves de Assis's family, who is 71 years old. For more than four decades, pain woke up with him, crossed his days, and accompanied him through sleepless nights. Fibromyalgia not only consumed his body but also stole his rest, mood, and sense of things. And, in silence, it also shaped his daughter's destiny.
Before becoming a doctor, Caliandra Patrícia Pinheiro Alves de Melo was a nurse. She spent six years caring for people and still felt incapable of alleviating the suffering of the one she loved most.
Nursing taught her care, touch, and presence. But it wasn't enough. She needed to deeply understand her father's condition, to decipher the disease that imprisoned him. It was from this daily, almost unbearable discomfort that the decision to study medicine was born.
When Care Was Not Enough
The path, however, was anything but romantic. Recently divorced, with a three-year-old daughter, Caliandra moved forward practically alone. It was a difficult few years, marked by exhaustion, fear, and sacrifices. Still, she did not give up. When she graduated, she felt invincible, as if she finally had the tools to give back to her father what the disease had taken away.
The reality was harsh. No combination of medications worked. Pregabalin, duloxetine, clonazepam, cyclobenzaprine, corticosteroids, analgesics. Nothing. The suffering persisted. And frustration accumulated within her, him, and the entire family that placed hope in that now-doctor daughter. The medicine she studied was not able to save the one who mattered most.
Living with 45 years of fibromyalgia left deep marks. Francisco lived with daily limitations, anxiety, depression, and interrupted nights. There was no pleasure or perspective. At times, he would say that it made no sense to live that way. For Caliandra, hearing this felt like carrying a double weight, his and her own.
The Plant, Faith, and the First Hope
In 2018, two years after graduating, a new possibility appeared. While researching alternatives, Caliandra came across medicinal cannabis. Still lacking technical mastery, courses, and robust studies available, she decided to give it a try. She bought an oil from a local association and began the most delicate part of the journey: convincing her father.

Prejudice was immediate. For a traditional, practicing Catholic from the countryside, cannabis carried the weight of sin. He resisted. He questioned. He feared judgment from others. "My daughter, I'm getting old, not crazy. Can you imagine me, after getting old, using marijuana? What will people think of me?" he would say.
The conversation was long, careful, supported by the few scientific foundations she had at the time. Acceptance came slowly. And, in secret, father and daughter also sought a symbolic blessing: they spoke with the parish priest. The answer was simple and definitive: the plant was from God, from nature, and was being used for the benefit of health. That phrase dissolved the guilt and opened space for hope.
Twenty days later, the change began to appear. A few drops a day. Francisco, who previously rated his condition between 8 and 9 on an intensity scale, began to report 3 or 4. Sleep improved. Mood transformed. Limitations felt lighter. He regained pleasure in small things and, surprisingly, abandoned all the allopathic medications he was using.
From Personal Experience to Professional Mission
For Caliandra, that was an irreversible milestone. As a daughter, she felt an immeasurable joy. As a doctor, she understood that she needed to learn for real. She could not turn patients into empirical experiences as she had done at home. It was necessary to study the endocannabinoid system, the CB1 and CB2 receptors, the pharmacology of the plant. And she studied.
Courses, certificates, nights of reading followed, always with the support of her partner Ítalo, who held her hand when it was necessary to pause other projects to continue learning. The search that began in the backyard of her own story turned into a professional mission. Today, there are about five thousand patients being followed, lives crossed by the same hope that once transformed her father's routine.
There is a phrase that Caliandra hears frequently and that moves her every time: "Doctor, thanks to you and the treatment with phytocannabinoids, I have returned to living." It is there that she feels that everything makes sense.

In 2024, life surprised her again. Her son, Bruno Henrique Pinheiro de Melo, then four years old, received a diagnosis of Autism Spectrum Disorder (ASD). Even being a doctor and treating autistic patients, the ground felt like it was missing. There were tears, fear, and silence. The fear of prejudice delayed the conversation with the family. But once again, the experience brought purpose.
Caliandra did not hesitate. The cannabis, which had already given life back to her father, would also be part of the care for her son. The treatment brought results. Today, Bruno is ASD level 1 support. Those who see him often do not even notice. And she knows: her mission now is also to embrace other atypical mothers.
Between her 71-year-old father and her 6-year-old son, Caliandra built a journey marked by limits, love, and science. A doctor who once felt incapable in the face of the suffering of those she loved most now brings more colors to the lives of thousands of people. And she continues to study every day to honor the origin of it all: the love that arises from vulnerability and insists on becoming care.
