Both neurosis and psychosis express in our psyche the revolt of the id, our instincts more ancestral, against the external reality whose end result is the inability to adapt to that objectivity that confines us. Neurosis and psychosis differ more in the first stage than in the final result: the neurosis flees from a fragment of reality and psychosis prefers to reconstruct it.
The neurosis appears by the imbalances between our aggressive and sexual instincts, our reasoning and the morality-filled norms imposed by our parents, if these imbalances are extreme psychosis appears.
We repressed to survive the chaos, the imbalance, but everything repressed returns unconsciously in the form of neurotic symptom because this suppression is not resolved affectively, the neurotic represses, psychotics dissociate. Denial is the first psychodynamic of psychosis, it is more than repression, psychotic there is no problem not only eliminate the fact but also erase the affective charge. In psychosis in a first time the person departs from reality dissociating and later appear attempts to recover that reality lost through delusions and hallucinations, has a weak self and occurs a depersonalization where the psychotic lives in his life a nightmare from which he can not awaken.
The energy we have used to defend ourselves from our conflicts between instincts and our reasoning is synonymous with resistance, the same energy we use to suppress will appear as a symptom later.
The price of our culture is to suppress and sublimate our conflicts, we heal when we understand our unconscious, the emotions enclosed there, since we behave from the unconscious not from the conscious part of our mind. Children base their emotional learning on what their parents feel not what they say, often being inconsistent, because of it the conflicts locked in the child’s psyche when growing, are usually repressed as in the case of the neurotic or can be dissociated as the psychotic does.
