Psychoanalysis in the study of the human psyche considers all processes in the psychodynamic paradigm. The term "psychodynamics" first appeared in the works of Freud. From the information given by Freud deduces the definition: psychodynamics is the mutual influence of unconscious (id, BSZ) and conscious (ego) processes in which BSZ is of priority importance [14]. The psychodynamic approach made it possible to reveal the economic features of mental processes. Psychic economism describes how psychic energy is involved in the processes of production/reproduction, distribution, transition and qualitative and quantitative changes. When describing psychodynamics and the economy of Freud focused on libido as the only psychic energy that can be invested in an object in a direct and sublimated form, and manifest itself in models of attraction or conversion, in symptoms. However, the study of mental processes in patients with borderline personality organization of psychogenic etiology with the help of hypnopsychoanalysis allowed us to change the view of libido as the primary and central mental energy. According to the data of psychocorrective work, we came to the conclusion that anxiety is a pre-libidinal energy that is first experienced by a child at the moment of birth and in the process of ontogenesis is able to convert into libido. This leads to the conclusion that libido is the result of the conversion of anxiety, or, in other words, the reactive formation of anxiety. For the first time, an attempt to give anxiety a basal status was made by Karen Horney [20]. However, her work describes the phenomenological aspects of anxiety. We find a broad study of anxiety in a phenomenological way both in early authors, among whom R. May is particularly noted [8], and in modern ones [5], [3], [7]. In turn, the report examines the economic aspect of anxiety in the psychodynamic approach, its genetic relationship with libido, and the ability of anxiety to convert into libido. The research methodology is based on the following: - analysis of sources that highlight the problem of anxiety; - philosophical justification of the singular and plural; - data obtained as a result of psychocorrective work using psychodynamic hypnotherapy
