Letter from a Patient

The very qualities that give a healthy human being the opportunity for a full and worthwhile life have, I believe, worked against me since late childhood. I was born June 10, 1943, in Vancouver, British Columbia, Canada, into an average, middle-class Protestant family. My intelligent, caring, responsible parents gave me and my two sisters the best of what they knew. They have always been hard-working, generous, and friendly people, who taught us good values to live by. We learned respectfulness, independence, and responsibility from them.
I was born with a good IQ, as well as other good qualities that could have given me a great opportunity for a successful life: naturally curious, determined, and friendly, with a healthy courage, and a passionate desire to strive for excellence in life. They are qualities that do not always make a person popular, therefore, difficulties would have followed me at the best of situations in life, I believe.
So what happened to my life? My story is a long and painful one, with myriad symptoms plaguing my life for nearly 48 years. My perception, memory, and intuition was precariously disrupted and distorted, and my emotional world was thrown about by depression, paranoia, anger, hostility, despair, and suicidal desires—while a mess of physical symptoms, from a poor immune system, also made my life, many times, a lonely and hellish trip.
All this drove me, at different times in my life, without rhyme or reason, into a strange psychotic world. It was not until I read Dr. Jonn Matsen's book, Eating Alive, in 1992, while working at Nature Works Natural Foods, in the town of Ganges on Salt Spring island, that I first learned of his clinic in North Vancouver: the North Shore Naturopathic Clinic. Eventually, seven years later, after my last total psychotic crash, I finally began to find the answers to a lifetime of misery.
As a teenager, I was considered a hypochondriac and a neurotic. At 31, when I had my first long-term psychotic crash, which lasted about four years, I was classified as a paranoid schizophrenic.
In late childhood, I was plagued with night panics, unreal fears, and loud ringing in the ears, which is still with me today. In my early teens, I began to suffer from extreme self-consciousness that would come and go; paranoia around my family and friends began to torment me, with a strange comfort when I was around strangers, sometimes. I had a fear of public places (agoraphobia), claustrophobia, nervousness, and fatigue; my teenage years and twenties were miserable, much of the time.
But a great desire for learning, I believe, took, what many times could have been a totally disastrous life, and continued it on the road to an answer. I have been through over 45 jobs in my life, as well as a two-and-a-half-year start at a navy career, where I became a sonar operator at 19, and worked on an Oceanographic Research base in Shelbourne, Nova Scotia. Eventually I trained new recruits from the Fleet Sonar School in Key West, Florida. I was plagued with one short bout of psychosis while in the navy, but was allowed to remain in the services, if I returned to my base. Which I did, as I surely did not want to leave the navy on the grounds of a mental problem.
I did finally leave the navy early to enter the Registered Nurses training program at the Vancouver General Hospital, in Vancouver, BC. But I left the nursing program after 14 months, as I was accepted at the University of British Columbia in the Pre-Med program, in September 1966—the real dream of my life. But I became depressed and paranoid by the end of my first university term, and had to drop out—with terrible emotional pain over the loss of my dream. I managed to eventually move on.
Because I was very good in bookkeeping, typing, and shorthand in high school, I eventually got a bookkeeping job in 1967. By 1970,1 was a senior bookkeeper, and started the Certified General Accountant's course at UBC at night school, while working full-time. I only managed two years of the course before my life started unravelling again.
In December 1974, while working as a junior accountant at a large cedar mill in Langley, BC, I finally crashed into four years of severe psychosis, which took me out of my accounting job and into a psychiatric ward for a couple weeks, and then into my parents' home, where they looked after me as long as they were able, which was about a year.
Trouble came, and into a prison remand section, I went in May 1976, in a terrible psychotic state. After two weeks, my family, lawyer, and forensic psychiatrist had me transferred into Riverview mental hospital. After six months of psychiatric treatment, and a five month trial for arson, I went on to a forensic ward, from which I was not finally released until October 1978.
These were horrible years, which nearly did me in. Four years of drug treatment—with Valium, then shock treatments, and finally anti-psychotic drugs—put a deeper shadow over my so-called illness, I believe, than had the original symptoms.
From the time I was released from the forensic hospital in October 1978, until my final serious psychotic crash in October 1998, which lasted four months, I had one minor collapse in the winter of 1984, with a mess of symptoms throughout the next nine years. Then came a more serious collapse in August of 1993, which lasted nearly two years, until the spring of 1995.
It was after the four months of psychosis, starting in October 1998, that I finally made an appointment to see Dr. Jonn Matsen at the end of January 1999. After being a patient of Dr. Matsen's for ten months, I found that all of my symptoms were starting to diminish, though they had not gone away totally. Dr. Matsen told me in November 1999 that I needed to go and get all the remaining mercury fillings out of my mouth, of which I had five or six.
I only had eight teeth of my own left. As a child I had soft teeth, and had many fillings before I was 25. At 25 I had all of my top teeth removed because they were soft and misshapen; I also had an accident in high school while playing grass hockey.
After having my fillings changed, I have had DMPS IV shots every month since the end of January 2000. My whole world has changed. The mental, emotional, and physical symptoms have nearly all
disappeared. The mercury and other heavy metals in my body are considerably lower now, and hopefully after a few more months, they will finally all be removed from my body.
The paranoia, anger, hostility, depression, psychosis, immune system problems, personality problems, and extreme self-consciousness have disappeared, as have a mass of other symptoms. I am left, at 57, with a sense of peace I have hardly ever known as an adult. But I am also left with a very different kind of anger: an anger over a terrible injustice that can tear a person's life to shreds for so long, for which no one is held responsible in our system.
