Neurosis and Psychosis Difference
Neurosis is when a person has a problem but they're aware that they have a problem. Psychosis is a mental impairment that is precipitated and sustained by a break with external reality.

However, the psychologically healthy person is able to tolerate the anxiety and resolve the conflict by making a decision and acting on it. The neurotic cannot do these things they cannot live of their mind they cannot have and we cannot tolerate the anxiety their feelings of conflict reduce.
What is The Difference Between Neurosis and Psychosis?
Their neurosis is their way of all in their conflict and their anxiety in check. They also defend themselves against awareness of them so they pretend that these problems do not exist.
An infant is not psychotic, the reason is that the infant's psychological integration is not simultaneously that of an adult and an infant. It is simply that of an infant, for this reason, the infant's psychological condition is integrated and healthy even though the infant's understanding of reality is more subjective and therefore more projective than that of the adult psychotic.
The adult psychotic on the other hand has the psychological architecture of an adult as well as that of an infant. The conflicts from which neurotics suffer usually arise in childhood. If parents give their child the impression that these feelings are bad or naughty.
If for example a is gonna permit him to express anger or even love the child will tend to view these perfectly normal feelings as dangerous. The child will simple repress them pushing them so far out of his consciousness that it does not need to feel a conflict between wanting to do something our fearing to do it, instead the child will develop a neurosis.

A set of symptoms it cannot control and does not understand and that impede is an ability to function in one are more important areas of his life, that only are is symptoms painful to him they're also frightening so frightening that a child may even believe is losing his mind.
Neuroses may lead to a blending of one's awareness of certain aspects of external reality, but any such loss of awareness is subordinate to loss of awareness of one's emotional condition. Similarly, psychosis may lead to a disruption of one's understanding of one's emotional condition, but any such disturbance is subordinate to the psychotics loss of awareness of external reality.
Though symmetrical in the just described respects neurosis and psychosis are ultimately not mirror images of each other. This is a consequence of the fact that psychosis involves a partial regression to a condition of psychological infancy, the operative term being partial.
The psychotic has two entirely distinct and incompatible ways of processing information, he does not have a unified value system. He does not have a unified understanding of how to implement such values as he has. His psychological condition is, therefore, one of utter disarray and therein lies the peculiarly damaging nature of psychosis, nothing comparable holds of the neurotic.
Neurosis is about containing threats to one's integration by repressing them, to repress a conceit is not to bury one's knowledge of it in the unconscious. It is rather to bury one's knowledge of its emotional valence in the unconscious. As a result, the neurotics condition is one of relatively unimpaired intellectual awareness.
In fact, in some circumscribed ways it may even be a condition of heightened intellectual awareness owing. The neurotic is likely to compensate for his impoverished emotional state by hyper collecting his intellect.

Moreover by stripping the contents of consciousness of their emotional valence 'as the neurotic guarantees that he is a hyper stable though also an ossified psyche the essence of psychosis is an inability to organize consciously experienced emotion.
The essence of neurosis is an inability to have consciously experienced emotion. The psychotic is paralyzed by a superabundance of emotion the neurotic is paralyzed by a lack of it. Neurosis is a far cry from psychosis, the neurotic is in good touch with reality the psychotic is not.
