It's not just a question of recognising our own state. How often are delusions really registered as such by others

We spoke about this at my group in reference to a horrible incident up here in Canada. Not even the people around the individual caught on to his being delusional until too late. How many people have we each encountered that is a bit odd that we chalk up to being eccentric? I myself had been behaving pretty extremely, was 'out there' and spending a great deal of money and not a single person in my life did or said anything.

Back to my own recognition, I am not so sure I would when it comes. I do second guess myself - anyone else? If my mood changes, or maybe I might find myself talking quickly, or maybe I get irritable I ask myself am I okay? it is annoying.
