Beware There is no Definitive Answer As To What Causes Mental Illness.
The human body is incredibly complicated organism. The origin of the Universe is simple by comparison.
No one knows for sure what causes mental illness!
Mental illness is thought to be caused by genetics and environment. Put another way, anything and everything.
I have no control over my genetics. I do however have a great deal of control over my environment. By environment I mean everything that is not my genetics.
Study after study has proven that controlling what I can control can have a tremendous effect on my mental and physical wellbeing.
Principally what I can control is what I put into the machine that is my body (food) and how much I move my body, (exercise).
Science knows a great deal about the effects of quality food and exercise on wellbeing. Medications and the interactions between them is mostly trial and error.
I have spent thirty years of my life doing research. Lately I have turned my attention to saving my own life. My take aways can be summed up pretty quickly:
Eat nutritious food.
Exercise as much as I am able to but at least a little bit each day.
Sleep seven to eight hours a night.
Reduce the stress in my life.
Will these four items cure everyone? Probably not. The do have the benefit of, for the most part, being within my control. They also happen to be empirically proven to to be effective with no negative side effects.
My physical well-being is inescapably tied to my mental health. My mental health is inescapably tide to my physical health.
For me being well is not just a matter or life and death; death is easy. Living in hell is hard.
I am now comfortable stating the if any health care provider suggests they have a solution to what ails me that did not include, attention to my diet, my level of physical activity, sleep and stress reduction, I will move on to someone who can read.
Trusted unbiased (to the extent that is possible) scientific literature is everywhere, any provider who doesn't avail themselves of what are essentially free resources is in my opinion guilt of negligence.
All but the most physically damaged people, and most of them too, can improve the quality of their life by embracing what we can change ourselves.
I looked for answers in a pill and it cost me everything but my life.
I hope everyone can find the peace they deserve. Life is to short to spend it in hell.
