You seem to draw a great many inferences from a very small conceptual base.
What is your definition of psychoanalysis? Do you differentiate it from psychotherapy in general? Do you limit the functional definition to the methods of a single practitioner, or a particular school - or what?
Psychoanalysis put aside the conscious processes of the subject.
Where did you get that? Have you any idea how many types, schools and methods of psychotherapy exist in the present moment - never mind how many others have gone in and out of favour over time?

It predicts that neurotic symptoms are the consequence of repression of instinctual desires in childhood.
Where is this "prediction" written?
What constitutes a "neurotic symptom"?
Neurotic symptoms are not the result of repressed desires but of the lack of channeling of anxiety and depression.
Thus spake -- who, exactly? On what evidence? What makes you think either of those causes is exclusive of the other, or, indeed of one or more other causes?
What is "channeling"? Why should it happen? How is it done? What are the underlying causes of "anxiety" and "depression"?
Those symptoms can be consciously managed with the help of the psychologist.
Indeed. In some, many and possibly most patients, some, many, and perhaps most undesired feelings, urges and behaviours can be "managed" by some form of cognitive therapy under the guidance of the appropriate psychologist, plus the appropriate dosage of the appropriate medication, for that particular patient with those particular symptoms - always keeping in mind that "manage" does not mean "alleviate" or "cure".
However, one cannot help but wonder whether all of those psychologists and therapies would be available today, without the pioneering work of Freud, Adler and Jung. It's facile - not to mention pointless - to dismiss the early theorists in a field for not making it complete and perfect in the process of inventing it.
