A psychiatrist has two tools in the box, drugs and feelings. They can medicate people which in most cases just papers over the underlaying problems or they can muddle around in the soulish area by analyzing your feelings about certain things but does any of that actually get to the root of the problem? Contemporary psychiatry as promolgulated by Freud and Jung does nothing about the root issues as these are beyond the scope of man to deal with. Indeed Freud, Jung and others were nuttier than fruitcakes themselves (IMO) and these men are the bedrock that modern psychiatry came from. As an example this is from the wiki on Freud and this was Freud's view of God;
'Freud regarded the monotheistic god as an illusion based upon the infantile emotional need for a powerful, supernatural pater familias. He maintained that religion — once necessary to restrain man’s violent nature in the early stages of civilization — in modern times, can be set aside in favor of reason and science.[93] “Obsessive Actions and Religious Practices” (1907) notes the likeness between faith (religious belief) and neurotic obsession.[94] Totem and Taboo (1913) proposes that society and religion begin with the patricide and eating of the powerful paternal figure, who then becomes a revered collective memory.[95] In Civilization and its Discontents (1930), he describes religion as an “oceanic sensation” he never experienced, (despite being a self-identified cultural Jew).[96] Moses and Monotheism (1937) proposes that Moses was the tribal pater familias, killed by the Jews, who psychologically coped with the patricide with a reaction formation conducive to their establishing monotheist Judaism;[97] analogously, he described the Roman Catholic rite of Holy Communion as cultural evidence of the killing and devouring of the sacred father.[98] Moreover, he perceived religion, with its suppression of violence, as mediator of the societal and personal, the public and the private, conflicts between Eros and Thanatos, the forces of life and death.[99] Later works indicate Freud’s pessimism about the future of civilization, which he noted in the 1931 edition of Civilization and its Discontents.[100]'
I as well have some issues and modern psychology would place a label of a schizoid personality disorder on me (similar to schizophrenia without the delusional aspects) but how can we understand anything about ourselves from so called professionals whose whole life view relegates even the notion of 'God' to fantasy? I wouldn't make a grand sweeping statement that there is nothing that such people might do to help you understand yourself but I certainly wouldn't look to them for any anwers. How can a discipline that rejects God at the heart of it do much to assist us in understand exactly what God is accomplishing in our lives? The Lord knows the issues we are dealing with and He has the answers for us alone. Unfortunately some things in life we just have to muddle through the best we can and trust that the Lord will indeed provide a light to our path even in the midst of our stumbling and frail steps.
