Hey,
There is absolutely no concrete evidence that you're not delusional. Until you can completely prove that you are, in fact, not delusional to the rest of the world, you will not be taken seriously.
You think we are wrong to believe that our reality is real? It affects us, and we affect it, so even though it might not be real, it doesn't matter. Even if it isn't real, which is completely a last ditch effort by every creationist to prove the existence of God, it still affects us to a degree that we must deal with it as it is.
