I always wonder if crazy people know they're crazy? It's the archetypical catch-22. For the record: I have no reason to suspect that I'm insane.
I don't think anyone is out to get me. I don't hear disembodied voices telling me to do anything. I have no urge to do anything out-of-the-ordinary that other people don't do. I dress normally, work, go to school, and generally fit into society just fine.
If I ever do go insane, I'll be able to look back to June 27th, 2004, and know that the trip wasn't yet underway.
Unless your backup fails... :)
Whoever you are: that's mean.
My wife is a clinical social worker, and during her college internship, she did a stint at the Rockland Psychiatric Center in New York. She remembers telling a patient that the voices he was hearing weren't real and couldn't hurt him. He looked at her, and replied, "They just said 'bullshit'"
I don't know if this is any indication of knowing you're crazy, but it always creeps me out!
I sometimes wonder what if you slowly go insane? At what point in the "journey" do you go from being sane to insane?
