I too am wondering on what basis you are convinced of this. Have you actually seen cameras? Signs of the technology and logistics necessary to film every aspect of your life? This would entail being followed your every waking moment for which it would be obvious to see the trail of people and devices. I would start searching for the truth rather than assuming it. What about the role of other people? Can you honestly say that every individual is part of this conspiracy? People in third world countries even? For that is what would be entailed if in fact you were the centre of a television show.
When it comes for example to your therapist, I'd like you to consider that whether being filmed or not, she is still a professional and thus has your welfare and best interests at heart.
Why you by the way? If you were the subject of a tv program why would you be the one selected?
