How can u tell if your awareness is down or you feel confused?

others, or... At the moment of the confusion, decreased awareness usually makes the person unable to recognize it (imagine a person insisting on driving drunk). Usually, retrospectively (like in delirium) the person may realize they acted confused in the past; or (like in cases of dementia) other people detect the confusion and the patient denies it. In short, usually you can not tell the difference.
