What classifies someone as crazy?

What makes someone so outside of reality and normal society that they can no longer be trusted with holding up the ideals that make our society what it is? 

Because that is all crazy is, isn't it? 

Just another way of saying that that person is no longer capable of keeping up the charade? 

I don't believe myself to be crazy.

But by saying that, doesn't that make me the crazy one? 

I really would prefer not to know. You see, the truth is, no matter what someone tells me I am always going to be the person I am. I am not going to change unless I will myself to do so.

 Sure, I may learn the appropriate response and I may learn to keep my mouth shut but those thoughts and feelings that keep me in some perpetual state of gloom and paranoia are always going to be present. 

There is no treatment, only training.
