My Sick Brain? What?

It is so much to swallow. It is not a radio in your head playing a live hate mail broadcast but one's own sick brain? How easy could you believe that? Am I supposed to believe I have a brain that went bad from too great a chemical imbalance?
At one time cutting off limbs was a treatment to prevent gangrene! Who says psychiatry is at state of the art yet? Do they recognize as phenomena that they call hallucinations? Do they realize psychosis may be signs of an over-creative mind forming its own explanations for events or even for "reality"? Emotional disorders they seem to get.
The brain as a radio set is easy to understand. It operates at a bandwidth with audiovisual signals and may even transmit and receive signals at a high frequency with a strong enough signal strength.
So my brain, abusing itself? Prove it. I do not believe it just because it is a convenient explanation instead of an undisclosed radio possessing secret society member is being allowed to bully and abuse someone for not being a hard worker like everyone else his age.
It all started decades ago with my messiah complex period. I thought I was Jesus reincarnate to fix the world's problems. I did not get far but soon was suffering radioactivity in my head of an abusive nature. That has gone on over the decades on and off since. I did think I had powers and put them to use at research, and at penalizing some of the world's notorious parties - perhaps that is why I was originally targeted for the radio abuses? Don't governments have a god-complex deciding who lives and who is executable too? I guess you need the strength of a standing military or a secret radio set to be allowed to choose who is punished and how much without suffering for it.
So my sick brain is ruining my life because it's their professional explanation for the phenomena in my head. Great one. It is supposed to be true because?
