Psychosis and Neurosis are virtual look a likes, difficult to distinguish outwardly.
The latter resembles a software issue that corrupts a computer system, whereas the former refers to a hardware issue.
In humans, it is said, a neurotic knows his handicap as a handicap knows if, for instance, one is lame or dumb, but a psychotic considers his state of perception as true, refusing to entertain a suggestion opposite of it.
Now coming to the two mental states, namely sensitivity which is a normal condition and hyper-sensitivity which is an abnormal condition of mind, it may be generally seen that a hypersensitive subject often keeps the environs in turbulence, especially on public platforms.
