I'm with lightbulb on this one. If you are thinking "am I crazy?" Then it's a very good chance that you're not. One thing about delusions with sz is called lack of insight. It's the inability to distinguish that you're have a delusion, which is why reality checking can be a very difficult thing.

Also delusions and psychosis can be products of other illnesses as well, including bipolar. Also, even if you have sz or bipolar or psychosis doesn't mean that dooms you. You can still live a totally normal life. It's not like in the movies where they lock you up anymore. And it doesn't mean you're going to lose all your ability to function. Mental illness is a spectrum, and taking steps toward wellness will keep you on the functioning side.
